Correct Answer - Option 4 : energy
Energy is correct answer
- According to the Faraday Law, the change in magnetic flux causes electric current.
- The direction of polarity of this induced emf is given by Lenz Law.
- So, Faraday law, along with concept of Lenz law is given as
\(e=-\frac{d\text{ }\!\!\Phi\!\!\text{ }}{dt}\)
Where dΦ = change in magnetic flux and e = induced e.m.f.
- The Lenz Law induces the concept of conservation of energy in Faraday Law.
- According to Lenz law the change in magnetic flux causes change in energy, which is balanced by the induced emf.
