Question

List 4 factors on which the magnitude of force acting on current carrying conductor depends on

Answer 1

The magnetic field produced by a straight current carrying conductor depends upon the following factors:

i) Current in the conductor: If the current in the conductor is increased, the deflection of the compass needle increases.

This shows that, the magnitude of the magnetic field produced at a given point is directly proportional to the current passing through the wire.

ii) Distance from the wire: When a certain amount of current is passed and, if the wire is moved away from the compass needle, deflection decreases.

This shows that the magnitude of the magnetic field produced by a given current in the wire is inversely proportional to the distance from the wire.
