Worksheet Practice with Induced Currents (Constant Area)
Refer to the following information for the next three questions.

Which side of this permanent magnet is north: left or right?

As the falling magnet approaches the coil in which direction will the current induced in the coil flow: clockwise or counterclockwise?
When the magnet exits the opposite side of the coil, which way will the induced current flow?
Refer to the following information for the next three questions.

NOTE: the needle will deflect according to the direction of the induced current:
• towards the left (clockwise current from B to A),
• towards the right (counterclockwise current from A to B).

In which direction will the galvanometer's needle deflect as the magnet approaches?

If the magnet were to be moved more rapidly towards the coil, what response would the galvanometer register?

When the magnet is withdrawn from the coil, back towards the left, in which direction will the galvanometer's needle be deflected?

Refer to the following information for the next three questions.

Two coils of wire are wrapped on opposite ends of a common metal bar. The left coil is part of a circuit containing a switch and battery while the right coil only has a galvanometer to detect the presence of currents.
Which coil is considered the primary coil?
When the switch is closed, what happens in the induction coil?

If the induction coil were to be wrapped in the reverse direction, which of the above choices would then be correct?

Refer to the following information for the next two questions.

The left coil contains a variable resistor and a battery. A clockwise current is being induced in the right coil.
In which direction is the current flowing in the primary coil?
Should the magnitude of the resistance in the variable resistor be decreasing or increasing to induce a clockwise current in the induction coil?
