MHT CET 2025 Physics question
Two similar wires of equal lengths are bent in the form of a square and a circular loop. They are suspended in a uniform magnetic field and same current is passed through them. Torque experienced by
Answer: (A)
Solution
The torque on a current loop is , so for the same current, field and orientation, . Let the wire length be . Square: side , area . Circle: , so and area $=π
