A circular coil of 30 turns and area `250 cm^(2)` is rotating about its vertical diameter with an angular velocity of 50 `"rad" // s` , when placed in a uniform magnetic field of strength 0.02 T, acting horizontally to its plane. Calculate the maximum voltage induced in the coil.

Text Solution

AI Generated Solution

To calculate the maximum voltage induced in the circular coil, we can use the formula for the induced electromotive force (emf) in a rotating coil in a magnetic field: \[ E_{\text{max}} = n \cdot B \cdot A \cdot \omega \] Where: - \(E_{\text{max}}\) = maximum induced emf (voltage) ...
