PLEASE ANSWER ALL PARTS a. A circular coil of wire with 7 loops and a radius of 0.041 m is placed inside a solenoid. The coil is aligned so that the normal to the coil is parallel to the magnetic field in the solenoid. The solenoid consists of 40000 loops of wire and is 0.18 m long. Initially a current of 0.5 A runs through the solenoid. The current is increased to 4.5 A over a period of 4.1 s....

A rectangular coil of wire N = 20 loops with sides a = 0.30m and b = 0.70m is positioned perpendicular to a uniform 0.55T magnetic field as shown below. It is quickly pulled from the field at constant speed perpendicular to B to a region where B drops abruptly to zero, At t=0, the middle of the coil in at the edge of the field. The total resistance of the loop in R = 46 ohms. It takes 0.0125...
