... It is possible to use a plotting compass to show the shape of the magnetic field around an electromagnet, in the same way as for a permanent magnet. At the same time, you can see the effect of changing the current; a compass will line up more stubbornly in a stronger field. From straight wire to elect ...

... In general, the composites show magnetoelectric relaxation at low bias fields. Details of the relaxation behavior between systems were not investigated. The magnetization as a function of the applied electric voltage shows magnetoelectric relaxation at a low magnetic field of 10G. At 3000G the magne ...

Rotational States of Magnetic Molecules
... Crystals of high-spin magnetic molecules came to the attention of physicists after Sessoli et al. [1] discovered that they behave as regular arrays of identical superparamagnetic particles [2]. The remarkable property of magnetic molecules is that their spin can tunnel between up and down directions ...

Magnetism
Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Every material is influenced to some extent by a magnetic field. The most familiar effect is on permanent magnets, which have persistent magnetic moments caused by ferromagnetism. Most materials do not have permanent moments. Some are attracted to a magnetic field (paramagnetism); others are repulsed by a magnetic field (diamagnetism); others have a more complex relationship with an applied magnetic field (spin glass behavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. These include copper, aluminium, gases, and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state.The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change.
