A magnetic needle is kept in a non uniform magnetic field . It experiences

A

may experience a force and torque

B

may experience a force but not a torque

C

may experience a torque but not a force

D

will experience neither a force not a torque

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`vectau=vecMxxvecB`
`vecF=mvecB`
couple of force may give torque but not force is zero.
`m=`pole strength depending on angle
`tau=0 ,tau ne0,& F=0,F ne 0`
