Question

The right-hand rule (RHR), as applied to solenoids, tells us the relationship between the coiling current and the magnetic field produced. Your fingers curve in the direction of the current (which follows how the wires are wrapped around in a circle). Your thumb then points in the direction of the magnetic field:

When applying the RHR for solenoids, first determine the how the current is flowing. This requires (a) a careful look at the windings and how they wrap around and (b) the direction of positive current flow which is sometimes set by a voltage source. Curl your fingers to follow the current through the windings. Finally, note where your thumb sticks out. Your thumb will point in the direction of the magnetic "north" field.

Following these steps, select the magnetic field direction for each of these solenoids:

Solenoid 1

Solenoid 2

Solenoid 3 Solenoid 4
