... Tout et al (2008) predicts that isolated WDs with magnetic fields higher than 3 MG are formed as a product of a binary system which has undergone a CE-phase and a merger between the two stellar components. In the case of the double WD formation channel for AM CVn systems we also expect that the accr ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
