A rectangular loop of sides 20 cm and 10 cm carries a current of 5.0 A. A uniform magnetic field of magnitude 0.20 T exists parallel to the longer side of the loop. a) What is the force acting on the loop? b) What is the torque acting on the loop?

Step-by-Step Verified Solution

**Answer:** (a) F=0F = 0 (b) τ=0.1 N m\tau = 0.1 \text{ N m}. **Step-by-Step Explanation:** (a) In a uniform field, the net force on a closed loop is zero. (b) A=0.2×0.1=0.02 m2A = 0.2 \times 0.1 = 0.02 \text{ m}^2. τ=iAB=5×0.02×0.20=0.02 N m\tau = i A B = 5 \times 0.02 \times 0.20 = 0.02 \text{ N m}.
