Question

A bar magnet is held stationary near a single turn loop of copper wire connected to a galvanometer (which measures the current flow), as shown here. The galvanometer needle does not deflect (meaning no current is flowing) because the magnetic flux through the coil does not change. the magnet is not in contact with the coil. the magnet is probably too weak to cause any noticeable effect.

Step 1

Faraday's Law of Induction states that a changing magnetic flux through a coil induces an electromotive force (EMF), which in turn drives a current if the circuit is closed. Mathematically, the induced EMF ($\mathcal{E}$) is given by: $$ \mathcal{E} = -N Show more…
