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.
