Magnetism Research
Magnetic Domain -
a portion of a ferromagnetic material where the magnetic moments are aligned with one another because of interactions between molecules or atoms.
Magnetic field -
a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle
Magnetic stone - a temporary disturbance of the earth's magnetic field, induced by radiation and streams of charged particles from the sun.
Magnetite -
a very common black iron oxide mineral, Fe3O4, that is strongly attracted by magnets: an important iron ore
Magnetometer - an instrument for measuring the intensity of a magnetic field, esp. the earth's magnetic field.
Magnetosphere - the outer region of the earth's ionosphere, where the earth's magnetic field controls the motion of charged particles
Permanent magnet - a magnet that retains its magnetism after being removed from an external magnetic field.
Polar reversal - Change in polarity of Earth's magnetic field
Solar flare - A sudden eruption of hydrogen gas on the surface of the sun, usually associated with sunspots and accompanied by a burst of ultraviolet radiation that is often followed by a magnetic disturbance.
Solar wind - an emanation from the sun's corona consisting of a flow of charged particles, mainly electrons and protons, that interacts with the magnetic field of the earth and other planetary bodies.
Solenoid - an electric conductor wound as a helix with small pitch, or as two or more coaxial helices, so that current through the conductor establishes a magnetic field within the conductor.
Steel - any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying according to composition and heat treatment: generally categorized as having a high, medium, or low-carbon content.
Temporary magnet – Magnets that act like a permanent magnet when they are within
a strong magnetic field, but lose their magnetism when the magnetic field is taken away
