Magnetism is a fascinating natural phenomenon that captivates the curiosity of both children and adults. At its core, magnetism is the force exerted by magnets when they attract or repel each other. It is an essential aspect of our everyday lives, from the tiny magnets that stick your artwork to the refrigerator to the massive magnets used in medical MRI machines. This guide will explore various fun and educational magnet experiments for kids, providing a hands-on way to learn about this invisible force.
At The Kids Point, we believe in making learning both fun and educational. Our goal is to inspire curiosity and creativity in children through interactive and engaging activities. These magnet experiments are a perfect way to introduce young minds to the wonders of science.
What Are Magnets?
Magnets are objects that produce a magnetic field, which is invisible but responsible for the most noticeable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. Magnets have two poles: the North Pole and the South Pole. Opposite poles attract each other, while like poles repel each other. This fundamental property is key to many magnetic experiments.
Safety First
Before starting any experiments, it is crucial to follow basic safety guidelines:
- Supervision: Children should always be supervised by an adult when handling magnets.
- Swallowing Hazard: Small magnets can be a choking hazard and are extremely dangerous if swallowed. Keep them away from young children.
- Electronics: Keep magnets away from electronic devices to prevent damage.
Exploring Magnetic Attraction and Repulsion
Objective
Understand the basic principles of magnetic attraction and repulsion.
Materials
- Bar magnets
- Iron filings (optional)
- Paper
Procedure
- Attraction: Give each child a bar magnet and ask them to explore which objects around them are attracted to the magnet. Common objects include paperclips, nails, and screws.
- Repulsion: Show how like poles repel by trying to push two North poles or two South poles together. They should feel a force pushing the magnets apart.
- Visualizing Magnetic Fields: Place a piece of paper over a bar magnet and gently sprinkle iron filings on the paper. Tap the paper lightly to reveal the magnetic field lines.
- Explanation: This experiment demonstrates how magnets attract materials containing iron and how they repel or attract other magnets depending on their poles. The iron filings help visualize the magnetic field, showing the invisible lines of force.
Magnet Fishing Game

Learn about magnetic attraction through a fun, interactive game.
Materials
- Small magnets
- Paperclips
- String

- Scissors
- Construction paper
- Markers
Procedure
- Preparation: Cut fish shapes out of construction paper and attach a paperclip to each one.
- Fishing Rod: Tie one end of a string to a stick or dowel to create a fishing rod. Attach a small magnet to the other end of the string.
- Game: Scatter the paperclip fish on the floor or in a shallow container. Use the fishing rod to catch the fish by attracting the paperclips with the magnet.
- Explanation: This game is a fun way to demonstrate how magnets attract objects containing iron. It also improves hand-eye coordination and can be turned into a competitive game by seeing who can catch the most fish in a given time.
Magnetic Slime
Objective
Create a slime that reacts to magnets and explore the properties of magnetic fields.
Materials
- White glue
- Liquid starch
- Iron filings
- Small magnets
- Mixing bowl
- Spoon
Procedure
- Make the Slime: In a mixing bowl, combine equal parts white glue and liquid starch. Stir until the slime forms.
- Add Iron Filings: Gradually add iron filings to the slime and mix thoroughly. The more filings you add, the more magnetic the slime will become.
- Play and Explore: Use small magnets to move and manipulate the magnetic slime, observing how it responds to the magnetic field.
- Explanation: The iron filings in the slime make it responsive to magnetic fields. This experiment provides a tactile way to explore magnetism and see how the filings align along magnetic field lines when exposed to a magnet.
Magnetic Maze
Objective
Use magnetic force to navigate a maze, enhancing problem-solving skills and understanding magnetic attraction.
Materials
- Shoe box lid or shallow box
- Paper
- Markers
- Small magnets
- Steel ball bearing or paperclip
- Tape
Procedure
- Create the Maze: Draw a maze on a piece of paper and tape it inside the shoe box lid.
- Maze Runner: Place a steel ball bearing or paperclip at the start of the maze.
- Navigate the Maze: Hold a magnet underneath the box and use it to move the ball bearing or paperclip through the maze without lifting the box.
- Explanation: This experiment illustrates how magnetic forces can be used to move objects through obstacles. It also helps children develop spatial awareness and problem-solving skills as they figure out the best path through the maze.
Floating Magnet Trick
Objective
Demonstrate magnetic repulsion in a visually engaging way.
Materials
- Ring magnets (with a hole in the center)
- Pencil or wooden dowel
- Tape or clay
Procedure
- Prepare the Stand: Secure the pencil or dowel upright using tape or clay.
- Stack the Magnets: Place one ring magnet on the dowel. Then, place another ring magnet on the dowel with the same poles facing each other (so they repel). The second magnet should appear to float above the first one.
- Observation: Experiment with adding more magnets to see how many can be made to float by repelling each other.
- Explanation: This trick demonstrates the principle of magnetic repulsion. The floating effect is created because the like poles of the magnets repel each other, counteracting the force of gravity.
Magnetic Levitation
Objective
Explore the concept of magnetic levitation and stability.
Materials
- Ring magnets
- Pencil or wooden dowel
- Strong magnets
- Tape
Procedure
- Prepare the Stand: Secure the pencil or dowel upright using tape.
- Arrange Magnets: Place one strong magnet on the base and one at the top of the dowel. Then, arrange ring magnets on the dowel with like poles facing each other, causing them to repel and float.
- Observation: Experiment with different configurations to achieve stable levitation.
- Explanation: Magnetic levitation occurs when magnetic forces counteract gravitational forces, allowing an object to float. This experiment helps children understand the balance of forces and the concept of stability in a fun and engaging way.
Magnetic Pendulum
Objective
Observe how magnetic forces can influence the motion of a pendulum.
Materials
- String
- Small magnet
