A conducting wire in the shape of a circle lies on the (x, y)-plane with its centre at the origin. A bar magnet moves with a constant velocity towards the wire along the z-axis (as shown in the figure below) · S V N Ө dA +Z - Observer facing the ring in the direction of arrow We take t=0 to be the instant at which the midpoint of the magnet is at the centre of the wire loop and the induced current to be positive when it is counter-clockwise as viewed by the observer facing the loop and the incoming magnet. In these conventions, the best schematic representation of the induced current 1(t) as a function of t, is (a) (c) 0 이 (b) (d) 0 0 A conducting wire in the shape of a circle lies on the (x, y)-plane with its centre at the origin.
