This includes activities such as arc welding with certain types of equipment, [28] and maintaining heavy equipment that may generate strong magnetic fields. Some medical procedures, particularly magnetic resonance imaging (MRI), involve very strong magnetic fields or other conditions that may damage pacemakers.
A Bitter electromagnet or Bitter solenoid is a type of electromagnet invented in 1933 by American physicist Francis Bitter used in scientific research to create extremely strong magnetic fields. Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas , as of 2011 [update] .
A perpendicular paramagnetic bond is a type of chemical bond that does not exist under normal, atmospheric conditions. [1] Such a phenomenon was first hypothesized through simulation to exist in the atmospheres of white dwarf stars [2] whose magnetic fields, on the order of 10 5 teslas, [1] could allow such interactions to exist.
Any change to the current through the magnet must be done very slowly, first because electrically the magnet is a large inductor and an abrupt current change will result in a large voltage spike across the windings, and more importantly because fast changes in current can cause eddy currents and mechanical stresses in the windings that can ...
Superconductive behavior under varying magnetic field and temperature. The graph shows magnetic flux B as a function of absolute temperature T. Critical magnetic flux densities B C1 and B C2 and the critical temperature T C are labeled. In the lower region of this graph, both type-I and type-II superconductors display the Meissner effect (a). A ...
