Electromagnets: Two Forces Team Up Resistive electromagnets, another type of temporary magnet, combine the powers of electricity and of magnetism to enormous effect. Although superconducting electromagnets, which we'll discuss soon, offer many advantages, certain laws of physics prevent them from reaching the field strengths electromagnets are capable of. Some of the world's most powerful resistive [...]
Superconducting Magnets: Power Unplugged Superconductivity is a very cool phenomenon in which electrical resistance is overcome with the help of very cold temperatures colder than anything this side of Pluto! Most superconducting magnets are made using an alloy called niobium-titanium "Ni-Ti" for short. You could think of it this way: In a superconducting current, the [...]
