QUESTION #32 Torque on a Current Loop
A uniform magnetic field of 2 times 10^-3 text T acts along positive Y-direction. A rectangular loop of sides 20 text cm and 10 text cm with current of 5 text A is Y-Z plane. The current is in anticlockwise sense with reference to negative X axis. Magnitude and direction of the torque is :

QUESTION #56 Magnetic Field at the Center of a Coil
Two circular coils P and Q of 100 turns each have same radius of pi text cm. The currents in P and Q are 1 A and 2 A respectively. P and Q are placed with their planes mutually perpendicular with their centers coincide. The resultant magnetic field induction at the center of the coils is sqrtx text mT, where x = [Use mu_0 = 4pi times 10^-7 text T m A^-1]
