QUESTION #32 Torque on a Current Loop
A uniform magnetic field of 2 × 10⁻³ T acts along positive Y-direction. A rectangular loop of sides 20 cm and 10 cm with current of 5 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 π 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 √(x) mT, where x = [Use μ₀ = 4π × 10⁻⁷ T m A⁻¹]
