Effect of Magnetic Fields in Water?
Ok, Thanks vk6kro.
Phrak- a 'supercooled' magnet is a magnetic superconductor. it is commonly chilled to temperatures as low as that of liquid nitrogen or liquid Helium. The advantage is that when they are superconductors (super cold) the level of resistance drops dramatically, allowing an enormous amount of power to flow through the wires which would normally cause the wire to melt or vaporize. the supercooled magnet still generates heat, but it is often minuscule. Google 'super conducting magnets'. they are often used in particle accelerators.
