Question

a wire carries a current of . the wire is formed into a single circular loop and placed in a magnetic field of intensity . find the maximum torque that can act on the loop.

Answer 1

The maximum torque that can act on the loop is 7.875 N-m.

Torque:

Torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque can also be thought of as the ability of something that is rotating, such as a gear or a shaft, to overcome turning resistance.

The formula of torque:

Torque(T) = I B A

B = magnetic field of intensity

I = current =

A = area of the wire

l = length of the wire

l = 2πr

r = l/2π

A = πr²

   = π(l/2π)²

   = l²/4π

T = l²/4π IB

   =( 1/4π) BIl²

    = (1/4π) 0.30 × 150 ×× 2.20

    = 7.875 N-m

Therefore the torque is 7.875 N-m.
