1.1. Diagram 1 shows a wire carrying a current located between two magnetic poles.

The direction of the current is into the page.

Diagram 1

(i) Draw an arrow on diagram 1 to show the direction of the force acting on the wire.

Assume that the magnetic field is uniform.

[2]

(ii) State two ways to increase the magnitude of the force on the wire.

1.2. Diagram 2 shows a flat circular coil carrying a current.

Diagram 2

On diagram 2, draw the magnetic field produced by the current in the flat circular coil.

1.3. Diagram 3 shows a negatively charged ion placed in a uniform magnetic field directed out of the page.

Diagram 3

The force exerted on the ion acts to the left due to the magnetic field.

Use the left-hand rule to determine the direction of motion of the ion in the magnetic field.
