When sufficient electrical current is conducted across the squid body, a voltage is generated proportional to the strength of any nearby magnetic field. Uses of Superconductors [Magnetic Resonance Imaging] MRI is a technique developed in the 1940s that allows doctors to see what is happening inside the body without directly performing surgery. The development of superconductors has improved the field of MRI as the superconducting magnet can be smaller and more efficient than an equivalent conventional magnet. Application Super computer - Without superconductor : large heat, large electric power use - with superconductor : no heat, small electric power use ß Particle colliders are very large running tracks that are used to accelerate particles (i.e. electrons, positrons, hadrons and more) to speeds approaching the speed of light before they are collided with one another. –The collision usually possess enough energy to split the particles into smaller particles. –Particle colliders were used to discover many sub - nuclear particles such as taus and neutrinos. ß They do this by cycling the particle using magnetic fields, continually increasing the speed of the particle. Application ¾ Particle Colliders High Temperature Superconductors Cuprate superconductors have been the focus of researchers because they conduct at relatively high temperature (Tc > 77K). In the Y, Ba, Cu, O compounds: Y, Ba, and O have oxidation states of +3, +2, and -2, respectively. This results in copper having mixed oxidation states +2 and +3. A similar result is obtained for the other materials. Their structures are related to that of perovskite (CaTiO3 ).
