Description
Why does a magnet moving through a coil light a bulb? Faraday's Law puts a magnet, a coil and a bulb on one screen, and dragging the magnet changes the bulb's brightness with speed, which makes induced current and magnetic flux tangible.
Turn on field lines, change the coil's turns and area, and verify the law with a voltmeter.
Drag the magnet: Move it toward or away from the coil and both bulb and voltmeter respond.
Field lines: See the magnetic field passing through the coil.
Change the coil: Turns and area are adjustable for comparison.
