A long solenoid, with its axis along the x axis, consists of 30 turns per meter

Question

A long solenoid, with its axis along the x axis, consists of 30 turns per meter of wire that carries a steady current of 1.2 A. A coil is formed by wrapping 20 turns of thin wire around a circular frame that has a radius of 8 cm. The coil is placed inside the solenoid and mounted on an axis that is a diameter of the coil and that coincides with the y axis. The coil is then rotated with an angular speed of 4pi rad/s. Determine the maximum emf generated in the coil. 2.3x10 -6V 2.3xl0 -4V 2.3x 10 -3V 2.3xl0 -2 V 2.3x 10 2V neither of the above

Explanation / Answer

2.3 * 10^-4 V i .e option B
