To show the principles of induction in the classroom, here are some fun experiments:
Moving Magnet and Coil: Let students move a strong magnet in and out of a coil of wire quickly. Use a voltmeter to show the generated voltage. Talk about how moving the magnet faster creates more voltage.
Induction Cooktop: If you can, use an induction cooktop to heat a metal pan. Explain that the cooktop uses alternating current to create a magnetic field, which makes electric currents in the pan.
Magnet in a Generator: Make a simple hand-cranked generator with a magnet and a wire coil. As students turn the handle, measure the voltage produced. This illustrates Faraday’s Law of electromagnetic induction.
These experiments are hands-on and help students understand the important ideas of induction and how it’s used in our everyday technology.
