The Long Straight Wire in the Figure Has Current I

Question 50

Multiple Choice

The long straight wire in the figure has current I = 1 A flowing in it.A square loop which has 10-cm sides is positioned 10 cm away from the wire as shown.The loop is then moved in the positive x-direction with a speed v = 10 cm/s.If the loop has a resistance of 0.02 ohms,calculate the magnitude of the magnetic flux through the loop the instant the loop is made to move.
