Question

A rectangular coil of sides 'l' and 'b' carrying a current I is subjected to a uniform magnetic field $\to B$ acting perpendicular to its plane. Obtain the expression for the torque acting on it.

Open in App

Solution

The net torque acting on the rectangular coil is $\to τ = I \to A \times \to B$
Where area vector , $\to A = l b^k$ and magnetic field, $\to B = B^k$
$∴ \to τ = I (l b^k) \times B^k = 0$
