Consider the situation shown in figure. If the closed loop is completely enclosed in the circuit containing the switch, the closed loop will show

Figure shows a horizontal solenoid connected to a battery and a switch. A copper ring is placed on a frictionless track, the axis of the ring being along the axis of the solenoid. As the switch is closed, the ring will

Consider the following statements:

(A) An emf can be induced by moving a conductor in a magnetic field

(B) An emf can be induced by changing the magnetic field

Consider the situation shown in figure. The wire AB is slid on the fixed rails with a constant velocity. If the wire AB is replaced by a semicircular wire, then the induced current magnitude will

Figure shows a conducting loop being pulled out of a magnetic field with a speed $v$. Which of the four plots shown in figure may represent the power delivered by the pulling agent as a function of the speed $v$?

A conducting square loop of side $l$ and resistance $R$ moves in its plane with a uniform velocity $v$ perpendicular to one of its sides. A uniform and constant magnetic field $B$ exists along the perpendicular to the plane of the loop as shown in figure. The current induced in the loop is
