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
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
Can step up transformer increase the power level?
- Ans 1: No,a step up transformer can not increase the power level,in actual transformer,due of dissipation of energy in the coil the output power is always less than input power,Therefore a step up transformer can't increase power level.
