For a coil having a magnetic circuit of constant reluctance, if the flux increases, what happens to the current?(a) Increases(b) Decreases(c) Remains constant(d) Becomes zeroThe question was posed to me by my college professor while I was bunking the class.My question is based upon Inductance in Terms of Flux Linkages Per Ampere topic in section Inductance in a DC Circuit of Basic Electrical Engineering

Answer»

The correct answer is (a) INCREASES

To ELABORATE: For a coil having a magnetic circuit of constant reluctance, the flux is directly proportional to the CURRENT. HENCE as the flux increases, the current also increases.
