Inducing an electric current in a single loop

Even in a single loop of wire, passing a magnet into it will create an electric current. The single loop will still have all the characteristics of how a solenoid interacts with magnets.

One single loop is still a solenoid

Follow the movement of a magnet into one loop:

Passing a magnet into a single loop of wire.

A current is induced in the loop when a motion exists between the bar magnet and the loop.

Inducing a current in a single loop of wire.

When the bar magnet is stationary with respect to the loop no current is registered on the galvanometer.

No movement of the magnet will not induce a current.

The galvanometer is moved in one direction as you go towards the loop but moving it in the opposite direction....

Moving a magnet away from a loop of wire.

....causes the galvanometer to also move in the opposite direction which means there is a change in current induced direction in the wire.

Inducing a negative current in a single loop of wire.
