When a magnet is passed through a coil there is a (changing/unchanging) magnetic flux through the coil that induces an electromotive force (emf) in the coil; the incoming flux is (equal/not equal) to the outgoing flux

Solution

When a magnet is passes through a coil there is a changing magnetic flux through the coil that induces an electromotive force in the coil. because change in the magnet field causes change in flux.

The inoming flux is equal to outgoing flux.
