However, as increace permeance is generally understood to reduce torque, striking a balance between demagnetization and torque can be challenging.

2) consists of the following four processes: (1) magnetization, (2) heat transfer, (3) demagnetization, and (4) heat transfer.
To study the effect of armature reaction on the demagnetization risk of ferrite magnets, we show in Fig.
Since the magnets are constantly attracted to one another when they are approaching, this method also makes it possible to eliminate partial demagnetization, which can otherwise occur with another method when the magnets first repel each other when they are approaching (Zezulka and Straka, 2008).
Technically the method is referred to as "adiabatic demagnetization of paramagnetic salts.
This last phase is called demagnetization phase as shown in Fig.
The paleomagnetic directions were calculated mainly from AF demagnetization plots, after discarding soft secondary magnetic components.
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.
