1) If the axis of a moving coil is kept parallel to the flux then the e.m.f. induced in the coil will be :

minimum

maximum

nill

one volt

Answer is:

nill

Explanation:

static

dynamic

induced e.m.f.

none of the above

Answer is:

become half of their former value

become four times of their former value

remain unaffected

become eight times of their former value

Answer is:

tungsten steel

cast iron

high carbon steel

silicon steel

Answer is:

Whenever the flux linking through a coil or a circuit changes, e.m.f. is produced

The direction of dynamically induced e.m.f. can be determined by applying Fleming's right hand-rule

Coefficient of coupling or tightly coupled coils is zero

The coefficient of self inductance is proportional to the square of the number of turns on it

Answer is:
