Coils and Electromagnetism. Demo using
Coils and Electromagnetism.
Demo using a coil and a magnet to product electromagnetism. I take a coil and connect it to a Galvanometer. When I bring the magnet into the coil slowly a small current is recorded on the Galvanometer. When I pull out the magnet another current is produced, this time in the opposite direction.
I demonstrate how changing the number of turns affects the current,
how turning the magnet around affects the current
how changing the speed of putting in the magnet changes the current
