Question

What is the angle between plane of eddy currents and the plane of magnetic field?

• A. ${60}^{\circ }$
• B. ${90}^{\circ }$
• C. ${180}^{\circ }$
• D. $0^{\circ }$

Answer 1

The correct option is B ${90}^{\circ }$

According to Lenz's law, the direction of eddy currents in a metal block is as shown below when upward varying magnitude magnetic field is applied.


From the figure, the angle between the plane of eddy currents and the plane of magnetic field is ${90}^{\circ }$.

Hence, option $\left(C\right)$ is the correct answer.
