List four factors on which the magnitude of the force acting on a current-carryingconductorin a magnetic fielddepends.

Answer»

Solution :Factors on which the force on a current-carrying conductor PLACED in a magnetic fielddepends are :
i] Strength of magnetic field : F `prop` B
ii] Strength of ELECTRIC current : F `prop` I
iii] Length of the conductor : F `prop`L
iv] Direction between current and magnetic field : `F prop sin theta`
Magnitude of the magneticforce is hence F = BIL sin `theta` .
