A wire with total resistance R is formed into a circle This circle is placed horizontally in the xy plane within the constant magnetic field in the z direction The change of the radius of the circle with respect to time is expressed by r r 2 0 5t The circle begins to contract at t 0 Assume that the resistance R does not change in this process For t 1 s find the magnitude and flow direction of the current formed in the circle CCW counterclockwise CW clockwise if we are looking from z towards 2 n 3 R 60 B 2 Tk ro 2 cm 0 3 mA CCW None of them 0 1 mA CCW O4V CW 0 6 mA CCW O 0 1 MA CW 0 6 mA CW 0 3 mA CW B
