2) consists of the following four processes: (1) magnetization, (2) heat transfer, (3) demagnetization, and (4) heat transfer.
Depolarization, demagnetization, thermal expansion, exchange, nonequilibrium, and anisotropy interactions can influence the dipole orientations and therefore the fields and the internal energy.
Technically the method is referred to as "adiabatic demagnetization of paramagnetic salts.
Samarium-cobalt (SmCo) magnets have the highest known resistance to demagnetization.
Stability of the remnant vector in these samples has been examined by subjecting the samples to AF and thermal demagnetization on a pilot basis.
Subjects include: fundamentals of electromagnetism and magnetic particles, fundamentals of magnetic testing, magnetic leakage field measurements, equipment used in magnetic testing, reference standards, demagnetization, metals testing, electric power applications of magnetic particle testing, magnetic testing of metals, infrastructure and aerospace applications, and chemical and petroleum applications.
It has an additional input that can be used to detect demagnetization of the inductive element, ensuring full utilization of the magnetic material and preventing hard switching of the current.
The researchers discovered that during routine use of 3T MRI machines at angles above 80, an unacceptable level of demagnetization was reached, causing permanent damage to devices with non-removable magnets, and creating the potential of exposing patients to undesirable magnetic forces.
In this case, adiabatic magnetization and demagnetization are isentropic processes; therefore, when the material is subsequently demagnetized, its temperature will return to its original, zero-field value.
These parts are especially suitable for free-wheeling, clamping, snubbing and demagnetization functions in power supplies and other power-switching applications.
We analyzed the directions of magnetization of 60 rock samples taken from borehole cores drilled within and in the vicinity of the structure using thermal and alternating field demagnetization.
Permanent Magnets resist demagnetization and require no electrical connections or cables.
