Physics Question on Electromagnetic induction
In the phenomenon of mutual induction, self induction of each of the coil persists Self induction arises when strength of current in one coil changes. In mutual induction, current is changing in both the individual coils
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false
If assertion is true but reason is false
Solution
Mutual inductance is the phenomenon according to which an opposing e.m.f. produces flux in a coil as a result of change in current or magnetic flux linked with a neighbouring coil. But when two coils are inductively coupled, in addition to induced e.m.f. produced due to mutual induction, also induced e.m.f. is produced in each of the two coils due to self-induction.
