  • A uniform magnetic field of 3000 G is established along the positive z-direction. A rectangular loop of sides 10 cm and 5 cm carries a current of 12 A. What is the torque on the loop in the different cases shown in Fig. 4.28? (image f )

4.24 - A uniform magnetic field of 3000 G is established along the positive z-direction. A rectangular loop of sides 10 cm and 5 cm carries a current of 12 A. What is the torque on the loop in the given case shown in Figure (f)? What is the force in each case?

The magnetic field is given as,

 \vec{B}=3000\ G \hat{k}=0.3\ T\hat{k}

Current in the loop = 12 Amp

Area of the loop = length\times breadth

The area under the loop (A)=0.1 \times 0.05 =0.005 m^2

\vec{A}=-0.005\ m^{2}\hat{k}

Since the area vector is in the opposite direction of the magnetic field the torque on the loop is zero. The force on the loop is zero.
