The magnetocaloric effect can be quantified with the following equation: = ((,)) ((,)) where is the adiabatic change in temperature of the magnetic system around temperature T, H is the applied external magnetic field, C is the heat capacity of the working magnet (refrigerant) and M is the magnetization of the refrigerant.
One variant, the Einstein–Szilard electromagnetic refrigerator used a Einstein–Szilard electromagnetic pump to compress a working gas, pentane. [2] Although the refrigerator was not a commercial success, the Einstein–Szilard pump was later used for cooling breeder reactors , where its inherent reliability and safety were important.
A miniature electromagnetic vibration energy generator was developed by a team from the University of Southampton in 2007. This particular device consists of a cantilever beam with a magnet attached to the end. The beam moves up and down as the device is subjected to vibrations from surrounding sources. [2]
EMF is defined as electromagnetic work done on a unit charge when it has traveled one round of a conductive loop. The energy could now be seen as stored in the electric field. This process uses energy from the wire with power equal to the electric potential times the total charge divided by time. Where ℰ is the voltage or EMF.

Recognising the machine's potential, IBM arranged for Liebert to debut his invention at the World Computer Conference in Philadelphia. [ 1 ] [ 2 ] In 1965, Liebert founded Liebert Corporation as the first manufacturer air conditioning units with temperature and humidity controls specific for computer room applications.
Gibson appliance advertisement, 1948. Gibson was founded by Joshua Hall in Belding, Michigan, in 1877 as the Belding-Hall Company selling cabinets that housed blocks of ice ().
Z machine cross section Z machine diagram The Z Pulsed Power Facility , informally known as the Z machine or simply Z , [ 1 ] is the largest high frequency electromagnetic wave generator in the world, operated by Sandia National Laboratories in Albuquerque, New Mexico .
