Martin Wilson Lecture 2 slide15 Pulsed Superconducting Magnets CERN Academic Training May 2006 Magnetization and Losses: General so work done on magnetic material M H in general, the change in magnetic field energy (see textbooks on electromagnetism) around a closed loop, energy dissipated in material I1I1 i2i2 work done by battery to raise current in solenoid first term is change in stored energy of solenoid I 1 L 21 is the flux change produced in loop 2 so battery work done on loop a2a2
