Energy losses in superconductive DC-electromagnets due to ferromagnetic movement

A DC-current, superconductive electromagnet is a source of the magnetic field in a separator matrix. This type of separator operates in a cyclic way. Therefore, it is appears as very important to ensure the electromagnet stability during operation, i.e. range of parameter changes that could maintain the magnet winding in the superconductive state. This means selecting parameter changes representing the magnet winding in the superconductive state.
