Alternately, anticlockwise then clockwise

Alternately, clockwise then anticlockwise

A current-carrying coil in a magnetic field experiences a turning effect. How can the turning effect be increased?

increase the number of turns on the coil

reverse the direction of the magnetic field

The diagram shows a coil of wire between the poles of a magnet. The coil consists of 20 turns of insulated wire. The coil is connected to a variable resistor and a power supply. How can the turning effect on the coil be increased?

by moving the poles of the magnet closer to the coil

by reducing the number of turns on the coil while keeping the current constant

by increasing the resistance of the variable resistor

by reversing the terminals of the power supply

What happens to the strength of a magnetic field as you move away from the magnet?

The strength of the magnetic field decreases.

The strength of the magnetic field increases.

The strength of the magnetic field doesn't change.

The strength of the magnetic field is doubled.

The magnitude of the force on a current carrying conductor in a magnetic field can be increase by all of the following EXCEPT

use wire with larger cross sectional area
