Assignment:
Question 1. The rectangular loop in the figure above moves towards the long straight wire with a velocity v. If a current I flows through the wire, what is the voltage induced in the loop when the coil is a distance b from the wire in terms of L, I, v, a and b? How to evaluates the values I = 5A, a = 2cm, b = 2cm, L = 5cm and v = 2ms-1.
Question 2. A circular coil of radius 5mm and containing 500 turns has a resistance of 50Ω. The coil is placed in a magnetic field of 1.5T with the field direction normal to the plane of the coil. If the coil is rotated through 180° How do we calculate the total charge which flows through the coil. (Assume that the resistance of any external device connected across the coil is negligible).
