Question

how does a magnet have to interact with a coil to generate current?
make physical contact
move through it
rotate outside of it
remain stationary inside it

Explanation:

This relies on electromagnetic induction: a current is induced in a coil only when there is a change in the magnetic flux passing through the coil. Moving a magnet through the coil changes the magnetic flux, while physical contact, stationary placement, or rotating outside without flux change does not generate current.

Answer:

move through it
