Question
In a coil with n turns, what happens to the induced
electromotive force (EMF) if the number of turns is doubled while the magnetic flux remains constant?Solution
According to Faraday's Law of electromagnetic induction, the induced EMF in a coil is proportional to the number of turns (n). Thus, doubling the number of turns while keeping the magnetic flux constant will double the induced EMF.
