For which of the following machines (devices) is Faraday's laws of electromagnetic induction NOT applicable?

The correct answer is option 4.

Faraday's laws of electromagnetic induction

Faraday’s first law of electromagnetic induction:

• It states that whenever a conductor is placed in a varying magnetic field, emf is induced, which is called induced emf. If the conductor circuit is closed, the current will also circulate through the circuit, and this current is called induced current.
• The first law is responsible for the working of DC and AC generators.
   

Faraday's second law of electromagnetic induction:

• It states that the magnitude of the emf induced in the coil is equal to the rate of change of flux that links with the coil. The flux linkage of the coil is the product of the number of turns in the coil and the flux associated with the coil.
• The first law is responsible for the Transformer.
