Name three factors on which the magnitude of the force on a current-carrying conductor placed in a magnetic field depends and state how does the force depend on the factors stated by you.

Solution:

The following are the factors that directly affect the magnitude of the force on a current-carrying conductor in a magnetic field:

(i) On the magnetic field’s strength B

When the magnetic field intensity is increased, the amount of the force on a current carrying conductor increases.

(ii) On the magnitude of current I in conductor

If the magnetic field strength is held constant, a larger current in the conductor will result in a larger force acting on it.

(iii) On conductor length l

The length of the wire in the magnetic field affects the magnitude of the magnetic force. The greater the force on the wire, the longer it is in the magnetic field.
