Question

Two circular coils are lying on a table beside one another; the coil on the right carries no current since it is not connected to a battery. A power supply makes 10[A] current go clockwise around the left coil. At time t=0, we start reducing the power-supply current smoothly (from 10[A]) by 1[A] per second. During the next 10 seconds, the coil on the right will: Answer a. carry a decreasing current counterclockwise b. carry a decreasing current clockwise c. carry an increasing current counterclockwise d. carry an increasing current clockwise e. carry a constant current counterclockwise f. carry a constant current clockwise g. have no current since not connected h. flip due to magnetic torque

Explanation / Answer

a. carry decreasing current in counter clockwise
