A metal ring of radius 5 cm and resistance .1 ohm is placed around a 500 turn solenoid of radius 3 cm and length of 10 cm. A power supply is the attached to the solenoid and turned on so that current in the solenoid increases form 0 to 1 A in 0.01 s.
a. What is the average current in this ring in this 0.01 s?
b. What is the current in the ring after this time, if the power supply is left on?
How would you do this question?
