If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. In this situation they act as a magnet - but only whilst in ...

The Sun is preparing for a major event: the reversal of its magnetic field. This phenomenon marks a turning point in the solar cycle, signaling the transition from solar maximum to solar minimum.

they are not repelled they lose most or all of their magnetism when they are removed from the magnetic field This means that you can only show that an object is a permanent magnet by checking if ...

It revolutionized the low-cost mass production of permanent magnets and ... coercivity — a measure of a magnet’s resistance to other strong magnetic fields,” explains Sagawa.

In between these full geomagnetic reversals, which can last up to 10,000 years, we find shorter disruptions to the Earth’s magnetic field. These events are known as geomagnetic excursions.

Such reversals in the Earth's magnetic field, they'd tell you, are, roughly speaking, as common as ice ages. That is, they're terrifically infrequent by human standards, but in geologic terms they ...

Indeed, the researchers I spoke with all thought that organisms would be able to adjust to an acute weakening or even complete reversal of the magnetic field. "My gut reaction is it's not going to ...

Not electromagnets, but those permanent magnet fixtures ... on shop-built magnetic switches, the magic is gone. As it turns out, the ability to nullify the powerful magnetic field from a bunch ...
