Question

The induced emf can be produced in a coil by

 A. moving the coil with uniform speed inside magnetic field 

B. moving the coil with non-uniform speed inside uniform magnetic field 

C. rotating the coil inside the uniform magnetic field 

D. changing the area of the coil inside the uniform magnetic field 

Choose the correct answer from the options given below: 

(1) B and D only 

(2) B and C only 

(3) A and C only 

(4) C and D only

Answer 1

(4) C and D only

Moving a coil inside a uniform magnetic field either with uniform or non-uniform speed doesn’t changes flux, so, no emf is induced.
