What is the phase difference between the flux linked with a coil rotating in a magnetic field and the induced emf produced in it?
Options
- A0
- B( 4 )
- C( 2 )
- D( )
Correct answer
C. ( 2 )
Step-by-step solution
Magnetic flux linked with coil rotating in magnetic field (B ) is given as ( =B A t ) ( ) Induced emf, (e= -d d t =- d d t B A t ) (=+B A t ) ( e=B A ( t- 2 ) ) Hence, phase difference between flux linked with coil and induced emf is ( 2 ).
