Answer / er. ankush miglani 9718151073

magnetis ckt doesnt cosume energy but it stores energy in
the form of current
its formula is something 1/2 i*iL
dont know the xacty formula`

Answer / sujeet kumar

magnetic circuit consume energy that is given by area under
BH curve

Answer / sudheer

Inductor does not consume energy but it stores energy in
form of magnetic field.But magnetic circuit consumes energy.
EX:TRANSFORMER.The magnetising current component and no
load loss component which are necessary for operation of
transformer causes some power loss given by (current)*
(voltage)*p.f

Answer / chaitanya

magnetic circuit is nothing but a inductive coil. Coil is
either copper or aluminium winding. A pure inductor
doesnot consume electrical energy. In practical, Dut
due to the internal resistance of materil used in
winding it consumes a little amount. But it can be
neglected

Answer / raj kumar

yes magnetic field consume energy due to little bit
inductance of material

Answer / swadesh kumar singh

The magnetic ckt consume a little bit energy bcos the
magnetic material having some inductance.to magnetise the
material it consume energy.
