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

Define motional emf and write its formula.

  • Ans 1: If a conductor moves through a magnetic field then due to change in magnet flux,an emf is induced across the ends of the conductor which is known as motional emf.
    e=vBL sin theta.

Question # 1

A glass rod of "L"Length is moving perpendicular to the applied magnetic field P with velociety v.Explain briefly about the induced emf in it.

  • Ans 1: Induced emf is zero.As glass rod is insulator and there are no free electrons to be shifted from one extreme to the other.Therefore there will be no effect of perpendicular magnetic field.The induced emf is only produced by moving a conductor across the magnetic field.
