Physics - ICS Part 2 Physics Chapter 15 Short Questions Preparation

Question # 1

Define induced emf and induced current.

  • Ans 1: If a conductor moves through a magnetic field then due to change in magnetic flux,an emf is induced across the ends of the conductor which is known as back emf.If the circuit is close it will cause an electric current which is called as induced current.

Question # 1

What happen to the current of a circuit if a load resistance of the circuit is much less than the power transferred?

  • Ans 1: The greater the load the larger the current is supplied by the generator,When the load resistance of the circuit is much less,small current is supplied by the generator.

Question # 1

Is it possible to change both the area of the loop and magnetic field passing through the loop and still have bo induced emf in the loop?Explain briefly.

  • Ans 1: Yes,it the plane of the loop is kept parallel to the direction of the magnetic field magnetic flux through the coil will be zero,no emf will induced in the loop either by changing its area or by changing the magnetic field.

Question # 1

A suspended magnet is oscillating freely in the horizontal plane.The oscillation are strongly damped when a metal plate is placed under,The magnet.Explain why its occurs.

  • Ans 1: The oscillating magnet produces change of magnetic flux close to it.The metal plate placed below it experiences the change the magnetic flux,As the result eddy currents are produced inside the metal.According to Lenz's law these eddy currents oppose the cause which produce it,So the oscillation of magnet are strongly damped.
