Question

A current carrying conductor PQ of length 2 m, mass 808 ×
10–3 kg and resistance 100 mΩ is kept in
uniform magnetic field of 4 mT
(a) Find the direction of current through conductor if the
conductor is balanced against its weight
(b) Calculate the potential difference that must be applied to the
conductor so that it remains in equilibrium in the magnetic field
against its weight
