2. Magnetic hysteresis - Wikipedia

   en.wikipedia.org/wiki/Magnetic_hysteresis

   Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely.

3. Axion Dark Matter Experiment - Wikipedia

   en.wikipedia.org/wiki/Axion_Dark_Matter_Experiment

   Axion Dark Matter Experiment. The Axion Dark Matter Experiment (ADMX, also written as Axion Dark Matter eXperiment in the project's documentation) is an experiment that uses a resonant microwave cavity within a large superconducting magnet to search for cold dark matter axions in the local galactic dark matter halo.

4. Vine–Matthews–Morley hypothesis - Wikipedia

   en.wikipedia.org/wiki/Vine–Matthews–Morley...

   The Vine–Matthews-Morley hypothesis correlates the symmetric magnetic patterns seen on the seafloor with geomagnetic field reversals. At mid-ocean ridges, new crust is created by the injection, extrusion, and solidification of magma. After the magma has cooled through the Curie point, ferromagnetism becomes possible and the magnetization ...

6. Homopolar motor - Wikipedia

   en.wikipedia.org/wiki/Homopolar_motor

   A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field. The resulting force being continuous in one direction, the homopolar motor needs ...

7. Force between magnets - Wikipedia

   en.wikipedia.org/wiki/Force_between_magnets

   Force between magnets. Magnets exert forces and torques on each other through the interaction of their magnetic fields. The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of ...
