A uniform magnetic field B is set up in a solenoid of radius a =.4m. B is directed out of the plane of the paper, and is increasing ar a constant rate of +.5 T/s. A conducting ring with resistance of 10 ohms and radius of .9m encircles the solenoid, with the center of the ring on the axis of the solenoid.
What is the size of the current induced in the metal ring?
What direction of the induced current in the ring? explain clearly.
