remanence

Often a single measure of remanence does not provide adequate information on a magnet.

If the moments are exactly opposed, the magnet has no remanence.

The general term for this problem is data remanence.

This remanence can also be very stable, lasting without significant change for millions of years.

The most important component of remanence is that acquired when a rock formed.

The section on complications gives further explanations for causes of data remanence.

Various techniques have been developed to counter data remanence.

See data remanence for a discussion of difficulties in completely erasing computer media.

These minerals have a much stronger response to the field and can have a remanence.

One way to look inside these materials is to add or subtract small increments of remanence.

Note that it still may be recoverable by special laboratory techniques; read about data remanence.

With the external magnetic field switched off, the remanence falls back to zero.

The articles data erasure and data remanence have additional information.

This remanent magnetization, or remanence, can be acquired in more than one way.

The Wohlfarth relations can be represented by linear plots of one remanence against another.

Data remanence - in which sensitive data are read after supposedly having been deleted.

Cooled in zero magnetic field, these materials have low remanence and coercivity.

Some remanence calculations for randomly oriented, identical particles are shown in Figure 5.

Most importantly for rock magnetism, they have remanence, so they can record the Earth's field.

At zero field strength, the magnetization is offset from the origin by an amount called the remanence.

The data remanence article provides citations to publications that investigate the security of shredding.

A steel core's remanence means that it retains a static magnetic field when power is removed.

However, the Earth's field is not large, and this kind of remanence would be weak and easily overwritten by later fields.

By accessing the entire hard drive, data erasure eliminates the risk of data remanence.

The S-shaped current is needed to improve over the simpler converters and deal efficiently with remanence.
