FIELD: electric engineering.
SUBSTANCE: in accordance to method for changing amount of energy in magnetic system, current is measured in at least one pair of windings of magnetic coil, while changed in one coil is electric current of one direction of current density vector, and in another winding electric current of opposite direction of current density vector is measured. Device contains magnetic coil containing at least one magnet with winding. Magnetic system contains at least one more winding, while at least two windings are made with possible connection as one pair of windings and are made with possibility of joint powering by currents of opposite directions, while it is possible to inject energy into at least one pair of windings and to eject energy from at least one pair of windings.
EFFECT: increased efficiency of parameter changes in magnetic system.
