3. A coil consists of 130 circular loops of wire of radius 4.4 cm. A current of 0.46 A runs through the coil, which is oriented vertically and is free to rotate about a vertical axis (parallel to the z-axis). It experiences a uniform horizontal magnetic field in the positive x-direction. When the coil is oriented parallel to the x-axis, a force of 1.2 N applied to the edge of the coil in the positive y-direction can keep it from...

An electric generator consists of a circular coil of wire of radius 1.0×10−2 m , with 20 turns. The coil is located between the poles of a permanent magnet in a uniform magnetic field, of magnitude 4.0×10−2 T . The B field is orientated perpendicular to the axis of rotation. The ends of the coil are connected via sliding contacts across a resistor of resistance 1.5 Ω. The peak current measured through the resistor is 1.0×10−3 A What is the...

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....
