Question

Given below are two statements: Statement-1: A current-carrying loop placed in a uniform magnetic field experiences a net force that is always zero. Statement-2: The torque experienced by a current-carrying loop placed in a uniform magnetic field is maximum when the plane of the loop is perpendicular to the magnetic field.

TestHub · Accepted Answer

Statement-1: In a uniform field the forces on a closed loop cancel: $F = I \oint d l \times B = 0$ . True.

Statement-2: $τ = MB sin θ$ , where $θ$ is the angle between $M$ and $B$ .

Plane of loop perpendicular to $B$ means $M ∥ B$ , so $θ = 0$ and $τ = 0$ (minimum). False.

Answer: B
