10 Cool Magnet Experiments For Curious Kids
Written by Smriti Dey | April 30, 2026
Introduction
Magnetism is an unusual topic in science education because it is invisible, goes against common sense, and is very interesting to kids from the moment they first feel the invisible push or pull between two magnets. This mix of mystery and physical sensation makes science experiments using magnets one of the best ways to teach kids abstract physics ideas through direct, memorable sensory experience instead of just telling them about them.
Parents can also easily and safely use magnets as a scientific tool at home. Standard ceramic and bar magnets are safe to use with no chemicals, don't need any special safety gear other than basic supervision, and give kids immediate, visible results that keep them interested in trying again and again. This ease of access makes science experiments using magnets really useful for learning at home when you don't have access to specialized equipment.
Hands-on magnet activities help kids learn how to think like scientists, make observations, and test their ideas. These skills will help them do better in science class. The NIH National Library of Medicine states that kids who do hands-on physical science activities on a regular basis show stronger analytical reasoning, confident scientific thinking, and more academic curiosity.
5 Science Experiments Using Magnets
1. Magnetic Fishing Game
One of the most fun science experiments using magnets for younger kids is the magnetic fishing game. This activity helps kids learn how to sort things into groups, test their hypotheses, and understand that invisible physical forces follow rules based on materials that are easy to see. The American Academy of Pediatrics says that hands-on discovery activities that give kids immediate, visible results directly boost their scientific curiosity, analytical reasoning, and long-term academic interest in all primary school age groups.
Materials Required
One bar magnet or a strong horseshoe magnet
A length of string approximately 50 centimetres
A wooden stick or pencil as the fishing rod
Paper clips, small metal washers, and small plastic objects mixed together
A shallow container or bowl
Steps
To make the fishing rod, tie the magnet tightly to one end of the string and attach the other end to the pencil or stick.
Put paper clips, metal washers, and plastic things in the shallow container and mix them up to make a collection of things that are both magnetic and not magnetic.
Before kids put the magnet in the container for the first time, ask them to guess which things it will attract.
Slowly lower the magnetic fishing rod into the container and watch what sticks to the magnet and what doesn't.
Put the things the child found into groups based on whether or not they are magnetic. Talk about why some materials react to magnetic force and others don't.
Observation
Metal things like paper clips and washers stick to the magnet right away, but plastic things don't change at all. This shows that the magnetic force only works on ferromagnetic materials. Kids can see that the magnet pulls things towards it without touching them, which makes the invisible nature of magnetic force directly visible through the activity.
2. Magnetic Poles - Attraction And Repulsion
The poles' attraction and repulsion experiment is one of the most conceptually rich science experiments using magnets that kids can do at home. This experiment helps students learn the basics of electromagnetism, how to think scientifically about what will happen in the future, and how to remember concepts through physical sensations. The NIH National Library of Medicine says that primary school children who learn science through physical sensations remember concepts better and understand science better than those who only observe experiments.
Materials Required:
Two bar magnets with clearly labelled north and south poles
A smooth flat surface such as a table or tray
Small paper labels for recording observations
A ruler for measuring repulsion distances
Steps
Put the two magnets on a flat, smooth surface about 20 centimeters apart, with the poles facing each other.
While the child lightly places a hand on top of one magnet, slowly slide it towards the other. The child will be able to feel the invisible force pulling or pushing through the surface.
To feel the repulsive force, turn one magnet 180 degrees so that the same poles are facing each other and then slowly move closer.
Use the ruler to find out how far away the forces of attraction and repulsion become noticeable during each approach.
Before each rotation, ask the child to guess what will happen and write down whether their guesses were correct.
Observation
Children feel a strong pulling force when opposite poles face each other and a strong pushing force when like poles come together. This is a direct physical experience of the basic law of electromagnetism. The force that we can't see becomes real when we feel it with our hands before we see it, making for a memorable multi-sensory science experience.
3. Magnetic Force Through Materials
One of the most interesting science experiments using magnets for kids aged eight and up is to see if force can go through different materials. This structured experiment cultivates scientific methodology, data documentation practices, and pattern recognition abilities essential for academic science. According to the Harvard Center on the Developing Child, the structured variable-testing activities directly improve children's working memory, cognitive flexibility, and systematic analytical thinking at all stages of primary and middle school development.
Materials Required:
One strong bar magnet or neodymium magnet
A collection of test materials: paper, cardboard, plastic sheet, aluminium foil, glass, fabric, and a thin wooden board
Small paper clips as the magnetic test objects
A recording sheet for systematic observation documentation
Steps
Put a paper clip on top of each piece of test material that is lying flat on a table.
Put the magnet under each material and slowly move it up towards the paper clip from below.
See if the paper clip moves when the magnet is under each type of material.
Clearly write down if the magnet's force went through each material, only partially went through, or was completely blocked.
Sort materials from most to least magnetically transparent based on what kids saw and talk about any patterns they found.
Observation
It was found that magnetic force easily passes through paper, cardboard, plastic, fabric, and glass but is only partially affected by thicker wooden and metal materials. This shows that magnetic field permeability depends on the type of material, not just its physical thickness. Kids learn that some metals block magnetic fields while others let them through. This is the beginning of more advanced ideas about magnetic shielding.
4. Homemade Compass Using A Magnet
One of the most useful science experiments using magnets for older kids is making a working compass from a magnetized needle. This experiment links physics concepts to real-world navigation technology, helps students learn how to follow instructions in order, and boosts their scientific confidence by making a working instrument out of basic materials. The NIH National Library of Medicine says that experiments that make useful tools for the real world get kids of all middle school ages more interested in science. It also helps them understand concepts better and keep their academic interest longer.
Materials Required:
One sewing needle
One bar magnet
A shallow bowl of water
A small piece of cork or flat foam approximately 2 centimetres square
A compass for verification of results after the experiment
Steps
With the sewing needle, stroke the magnet's surface firmly from eye to tip about 30 to 40 times in one direction only. Don't change the direction of the stroke while the magnetization process is going on.
Carefully put the magnetized needle on top of the small piece of cork or foam, making sure it is flat and balanced and doesn't tilt.
Put the cork and needle assembly on the surface of still water in the shallow bowl and let it float without making ripples.
As the needle lines up with Earth's magnetic field, watch it spin until it points towards magnetic north.
Check the direction of your homemade compass against a store-bought compass to make sure it was magnetized correctly and is pointing to the right magnetic north.
Observation
The magnetized needle moves on its own until it is in line with Earth's magnetic field. It always points to magnetic north, no matter how the bowl is turned or moved. Kids see that the needle stays in the same position after the first rotation stops, showing that Earth's magnetic field always pushes magnetized objects in the same direction.
5. Magnetic Slime Experiment
Magnetic slime is one of the most visually stunning science experiments using magnets. This multisensory experiment enhances tactile sensory processing and scientific observation, fosters comprehension of magnetic force distribution in mixed materials, and yields enduring visual outcomes that reinforce conceptual learning. The American Psychological Association verifies that multisensory scientific activities help kids of all ages in primary and middle school remember concepts better, get more excited about science, and stay curious about schoolwork for longer.
Materials Required:
White school glue (120ml)
Liquid starch (60ml) for slime activation
Iron filings (available from science supply stores or online retailers)
A strong neodymium magnet
Disposable gloves for handling iron filings safely
A mixing bowl and spoon for preparation
Steps
Put some white school glue and liquid starch in the mixing bowl and mix them together until they are completely smooth and stretchy.
While wearing disposable gloves, slowly add iron filings to the slime mixture and mix well until the filings are evenly spread out throughout the slime.
Place the magnetic slime on a flat surface and bring the neodymium magnet about five centimeters above the slime surface.
Watch as the slime stretches, reaches, and moves towards the magnet. This happens because the magnetic field pulls iron particles out of the slime matrix.
While the slime follows, move the magnet slowly across the surface. Then, quickly pull the magnet away and watch how quickly the slime goes back to its resting position.
Observation
The magnetic slime visibly stretches towards the magnet that is coming closer, showing that ferromagnetic particles mixed in with a non-magnetic medium keep their own magnetic responsiveness. Kids can see that the slime moves fastest when the magnet is closest and slows down as it gets farther away. This shows how the magnetic force gets weaker as the distance increases.
Conclusion
Science experiments using magnets give kids a direct, memorable way to learn about electromagnetic principles through safe, easy-to-do activities that no textbook can match. Kids who learn about magnetic force by doing hands-on experiments get better at scientific reasoning, more confident analytical thinking, and real curiosity about the unseen forces that shape the world around them every day.
