Four experiments with magnets

These four fun science experiments using magnets are quick and easy to set up, suitable for learning at home or school. Your students will measure the effects of magnetism as magnets pass through tubes made of different materials; create a visual demonstration of Chaos theory with magnets affecting the swing of a pendulum; feel “attract” and “repel” forces of magnetism by placing magnets on either side of their hand, and use the magnetic field to make an object move as if it is alive.

These four practical experiments demonstrate various different scientific principles related to magnets and magnetism, including:

• electromagnetic induction
• magnetic fields
• chaos theory.

This activity could be used as a starter or main activity to introduce the effects of magnetism and magnetic fields, or as one of several activities within a wider scheme of learning focusing on different types of forces. These experiments could also be used as an introduction to power generation or the potential uses of magnets in Design and Technology and Engineering projects.
