A circular coil of wire has 35 turns of wire each with a radius of 20 cm. The circular coil rotates with an angular velocity of 35 rotations per second. The circular coil has a net resistance of 0.25 Ohms. Next to the coil of wire is a long straight wire 45 cm from the center of the circular coil. The straight wire carries a current of 8.5 amps A) Calculate the mutual inductance due to the field at the center of the circular loop (7 points) B) Calculate the current induced in the circular loop (6 points) C) If you were to change the setup, such that the circular loop of wire were stationary and positioned as shown below, what would the rate of change of the current in the straight wire have to be in order to get the same induced EMF in the circular coil (12 points) 45 cm A circular coil of wire has 35 turns of wire each with a radius of 20 cm.
