A coil is placed in a magnetic field. What should be its orientation with the field for the flux to be
maximum ? When is it taken to be positive and when as negative?

A coil is placed in a magnetic field. What should be its orientation with the field for the flux to be minimum ?

A current carrying loop free to turn is placed in a uniform magnetic field vecb . What will be its orientation relative to vecB in the equilirbium state?

When is the magnetic flux linked with a coil held in a magnetic field zero?

What should be orientation of a magnetic dipole in a uniform magnetic field so that its potential energy is maximum?

A short bar magnet experiences a torque of 0.012 Nm, with its axis placed at 60^@ with a uniform magnetic field of 0.4 T. What orientation of the magnet corresponds to its stable equilibrium in the magnetic field? Calculate the Potential energy in this position.
