Question
The direction of induced e.m.f. can be found by:
- Laplace's law
- Lenz's law
- Fleming's right hand rule
- Kirchhoff's voltage law
Solution
To determine the direction of the induced electromotive force (e.m.f.), we should refer to the correct principle involved in electromagnetic induction.
Answer
The direction of the induced e.m.f. can be found by Lenz's Law.
Lenz's Law states that the direction of the induced current (and hence the induced e.m.f.) will be such that it opposes the change in magnetic flux that produced it. This law is a consequence of the conservation of energy and is fundamental in understanding how inductive circuits operate.
Therefore, the correct answer from the options provided is Lenz's Law.
