Unformatted text preview: opposite directions in the two wires. The wires are separated by a distance 2 a . A circular conducting ring of radius a in the plane of the parallel wires lies between the two straight conductors and is insulated from them. Find the mutual inductance between the circular conductor and the two straight conductors. 4. A solenoid has an air core of length 0.5 m, cross section 1cm 2 , and 1000 turns. a. Neglecting end effects, what is the selfinductance ? A secondary winding wrapped around the center of the solenoid has 100 turns. b. What is the mutual inductance ? A constant current of 1A flows in the secondary winding and the solenoid is connected to a load of 10 3 ohms. The constant current is suddenly stopped. c. How much charge flows through the resistance ?...
