demagnetization
demagnetisation BrE

This method of demagnetization is new to the industry and only available from a single manufacturer.

Depending on the demagnetization factor, one may obtain an intermediate state.

One other way of achieving demagnetization is to use an electric coil.

To remove this component, some form of stepwise demagnetization must be used.

One application of demagnetization is to eliminate unwanted magnetic fields.

Therefore demagnetization is sometimes used to keep magnetic fields from damaging electrical devices.

The process is the same as demagnetization. '

In addition to magnetization, there is also demagnetization.

Demagnetization is the process by which the magnetic field of an object is reduced or eliminated.

Progressive demagnetization is used to discriminate between the components to identify the primary magnetization.

One technique used for demagnetization is to heat the object above its Curie Temperature.

For permanent magnets a wide hysteresis curve is needed so that demagnetization should not easily occur.

He also modeled frequency-dependent susceptibility and alternating field demagnetization.

In this case energy of the demagnetization field does not impact the micromagnetic structure of wall.

BUT the big problem is demagnetization.

"This is what the pros worry about, not demagnetization," Mr. Davies said.

Over time these organized particles gradually become more random, a process known as demagnetization that is hastened by heat, humidity and oxidation.

This is also known by low temperature physicists as adiabatic demagnetization, due to the application of the process specifically to create a temperature drop.

Fortunately there is a very powerful alternative for cooling below 2 mK and that is nuclear demagnetization.

Activation requires demagnetization.

Strung along the submarine's gunwales were two parallel sets of demagnetization cables, running from the stern to the bow planes.

Storing tapes near electromagnetic fields, like those in televisions, computers, refrigerators or electric motors, can cause much more rapid demagnetization.

The mixed cases are possible as well when demagnetization field changes the magnetic domains (magnetization direction in domains) but not the domain walls.

Magneto-acoustic tags require demagnetization.

This means alnico can produce a strong magnetic flux in closed magnetic circuit, but has relatively small resistance against demagnetization.

The magnetic signature is reduced by the presence of a demagnetisation belt.

The shear is also readily identified from the aerial magnetic data as zones of demagnetisation.

The magnetisation and demagnetisation (where not demagnetised thermally) occur through intermediate states as shown (right).

According to the RATP, ticket demagnetisation affects 0.5% of tickets sold.

The first utilizes a helium dilution refrigerator to get to temperatures of millikelvins, then the next stage uses adiabatic nuclear demagnetisation to reach picokelvins.

One technique used to reach very low temperatures (thousandths and even millionths of a degree above absolute zero) is adiabatic demagnetisation, where the change in magnetic field on a magnetic material is used to provide adiabatic cooling.

Demagnetisation progressively occurs if the magnet is subjected to cyclic fields sufficient to move the magnet away from the linear part on the second quadrant of the B-H curve of the magnetic material (the demagnetisation curve).
