Physics for IGCSE & O level - Magnets And Currents (Section 3 - No. 35)
What happens when a magnet is pushed into a coil?
An e.m.f. is induced in the coil.
The coil explodes.
The magnet is repelled.
Nothing happens.
Vysvětlení
Moving a magnet into a coil induces an electromotive force (e.m.f.) and therefore a current, in the coil, as per Faraday's law of induction.
