A solar magnetic reversal means there`s no need to flip
... magnetic field flips over on a regular basis, roughly every 11 years. (Actually, Earth's flips too, very irregularly. The last time was 780,000 years ago. But that's another story.) How will Earth weather solar storms while the sun flips its magnetic field? Credit: NASA Goddard Photo and Video ...

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.
