A conducting rod AB moves parallel to X-axis in a uniform magnetic field, pointing in the positive X-direction. The end A of the rod gets

A coil in a simple generator has 200 turns.Now the number of turns in the coil increases to 500. What will be its effect:

Consider a current carrying coil placed in a magnetic field. What are the requirements for induced current to flow as per electromagnetic induction.

Which of the following will not increase voltage in a simple generator?

A jet plane is travelling towards west at a speed of 1600 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earths magnetic field at the location has a magnitude of 5 $$\times 10^{-4}$$ T and the dip angle is $$30^o$$.

The back emf in a DC motor is maximum when

What is the self inductance of a coil in which an induced emf of $$2V$$ is set up, when the current is changing at the rate of $$4As^{-1}$$

You have a coil and a bar magnet. You can produce an electric current by:

The current produced in a closed coil, where magnetic lines of force rapidly change within it is called:

A straight conductor 0.1 m long moves in a uniform magnetic field 0.1 T. The velocity of the conductor is 15 m/s and is directed perpendicular to the field. The emf induced between the two ends of the conductor is:
