Kamla peddles a stationary bicycle, the pedals of which are attached to a 100 turn coil of area `0.10 m^(2)`.The coil rotates at half a revolution in one second and it is placed in a uniform magnetic field of 0.01 T perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil ?

Text Solution

AI Generated Solution

To solve the problem, we need to calculate the maximum voltage generated in a coil that is rotating in a magnetic field. We will use the formula for the maximum voltage (E) induced in a coil, which is given by: \[ E = n \cdot B \cdot A \cdot \omega \] where: - \( E \) = maximum voltage (in volts) - \( n \) = number of turns in the coil - \( B \) = magnetic field strength (in tesla) ...
