We apply the right-hand rule. The thumb points in the direction of the current, other fingers in the direction of magnetic field.
To do this, grip coil A with the right hand in a manner that the thumb points in the counterclockwise direction.
Two closed loops A and C are close to a long wire carrying a current
(a) Find the direction (clockwise or counterclockwise) of the current induced in each loop if/is steadily decreasing.
(b) While/ is decreasing, what is the direction of the net force that the wire exerts on each loop?
