Magnetic Reconnection
... When the IMF has a southward component, conditions are favourable for magnetic reconnection to occur at or near the subsolar magnetopause. If reconnection occurs, the newly ‘open’ field lines have one end in the solar wind and the other in the ionosphere, and are highly kinked as they pass through t ...

Moving Electrons
... What causes batteries to go dead? How can you recharge them? In an electromagnet, the movement of electrons in a wire creates a magnetic field. Do you think the opposite is possible—could a moving magnet make electrons move? How do we make the “moving electrons” in the Advanced Light Source (ALS) do ...

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.
