A rectangular current carrying loop PQRS is kept in a uniform magnetic field as shown in the figure.

(a) What is the direction of magnetic moment of the current loop?
(b) When is the torque acting on the loop
(i) maximum, (ii) zero?

(a) Two straight long parallel conductors carry currents I_(1) and I_(2) in the same direction. Deduce the expression for the firce per unit length between them. Depict the pattern of magnetic field lines around them. (b) A rectangular current carrying loop EFGH is kept in a uniform magnetic field as shown in the figure. (i) What is the direction of the magnetic moment of the current loop ? (ii) What is the torque acting on the loop (A) maximum, (B) zero ?
