Q9 of 104 Page 304

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


Formula used: The emf developed across the ends of the loop is given by


Where v is the speed


B is the magnetic field


L is the length


The power delivered to the loop is



Where P is the Power delivered to the loop


R is the resistance


is the emf induced




From the above equation, P is proportional to v2. Curve b showing this relation.

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

Two circular loops of equal radii are placed coaxially at some separation. The first is cut and a battery is inserted in between to drive a current in it. The current changes slightly because of the variation in resistance with temperature. During this period, the two loops

A small, conducting circular loop is placed inside a long solenoid carrying a current. The plane of the loop contains the axis of the solenoid. If the current in the solenoid is varied, the current induced in the loop is
