A shown 'L' shaped frame is rotating with constant angular velocity 2 rad/sec about O inside uniform magnetic field 1T. Find magnitude of $V_{B} - V_{A}$ (in Volt).

Answer:

9.00

Solution:

$V_{B} - V_{A} = \frac{1}{2} B ω (5^{2} - 4^{2})$

$= \frac{1}{2} \times 1 \times 2 (25 - 16) = 9$

So, $V_{B} - V_{A} = 9$
