- When you move a magnet through a 1 loop coil you detect a voltage of 0.001 volts, what voltage would you read if you move the same magnet at the same velocity through a coil with 1000 loops (assume the radius of the loops in the coil is the same as the one in the single loop wire)a Figure 9 shows a single-loop DC motor. Determine the direction of rotation of the loop. (12.6) Figure 9 b) What should the external magnet poles be in order for the motor in Figure 10 to spin counterclockwise? (12.6) TA Figure 10An inductor consists of 100 turns of wire tightly wound about an insulating core. It is attached to a power supply and when the current through it is increased from 0 to 5 A in 3, s an induced emf of 5 V is measured. Find the inductance of this device and the magnetic flux and the energy stored in the magnetic field when the current is held steady at 5 A.

The coil moves into a uniform magnetic field B with constant velocity v. Find the magnitude and direction of the total magnetic force on the coil (a) as it enters the magnetic field (i.e. partially immersed), and (b) as it moves (totally immersed) within the magnetic field.

Explain why it would be better to improve the power factor as a method of improving the motor’s output, rather than to increase the voltage input.A motor is designed to operate on 117 V and draws a current of 12.2 A when it first starts up. At its normal operating speed, the motor draws a current of 2.30 A. Obtain (a) the resistance of the armature coil,(b) the back emf developed at normal speed, and (c) the current drawn by the motor at one-third of the normal speed.
