Questions
A magnetic dipole is free to rotate in a uniform magnetic field. For what orientation of the magnet with respect to the magnetic field.
a) Torque is maximum b) Potential energy is maximum
detailed solution
Correct option is C
We know torque τ=MBsinθ If θ=900 τmax=MB Also, P.E=- MBcosθ If θ=1800P.E = +MBHence key (3) is correctTalk to our academic expert!
