Question

The ammeter measures a current in the wire loop. What is driving the current?

A. Moving the magnet towards the loop changes the magnetic flux through the loop, thus inducing a potential difference across the ends of the wire loop that drives the current.

B. Moving the magnet towards the loop induces a magnetic flux in the wire that drives the current.

C. Holding the magnet near the wire loop pushes the electrons through the wire loop, thus causing the current.

D. Moving the magnet towards the loop induces a certain magnetic flux through the loop that drives the current.

Explanation / Answer
