MHT CET 2026 Physics question
A wire length L is bent in the form of a circular coil and current 'i' passes through it. This coil is kept in magnetic field. The torque acting on the coil will be maximum, when the number of turns is
Answer: (A)
Solution
If the wire of length is wound into turns, each turn has circumference , so and the area of each turn is . The maximum torque is \dfrac{L^2}{4π N^2}$ =
