As shown in the figure, a straight wire carries a current I into the page. The wire passes through the center of a toroidal coil. If the current I is quickly reduced to zero, the direction of the induced current through the resistor R is
• from b to a.
• from a to b.
• No current is induced.
• from b to a.
• from a to b.
• No current is induced.
