Question

Two rods of equal length L are welded together to make T shape structure. This structure is rotated in uniform magnetic field B at angular velocity $\omega$ as shown in figure. Potential difference between a and b is

• A. $\frac{B\omega L^2}{2}$
• B. $\frac{5}{4}B\omega L^2$
• C. $B\omega L^2$
• D. Zero

Answer 1

The correct option is D Zero


a and b are at same potential
So $V_{ab}=0$
