Detailed Solution
Download Solution PDFThe correct option is 3
Explanation:
Lenz's Law –
- According to this law, the direction of induced emf or current in a circuit is such as to oppose the cause that produces it.
- This law gives the direction of induced emf/induced current.
- This law is based upon the law of conservation of energy.
Lenz's law: When a voltage is generated by a change in magnetic flux according to Faraday's law, the polarity of the induced voltage is such that it produces a current whose magnetic field opposes the change which produces it. It is the consequence of the law of conservation of energy
Considering Lenz's law,
\(E = - N\frac{{d\phi }}{{dt}}\)
Hence the correct option is Energy.
