| magnetoencephalography |
Magnetoencephalography (MEG) is the measurement of the magnetic fields produced by electrical activity in the brain, usually conducted externally, using extremely sensitive devices such as SQUIDs. Because the magnetic signals emitted by the brain are on the order of a few femtotesla (1 fT = T), shielding from external magnetic signals, including the Earth's magnetic field, is necessary. ...

| magnetic flux |
Magnetic flux, is a measure of quantity of magnetism, taking account of the strength and the extent of a magnetic field. The flux through an element of area perpendicular to the direction of magnetic field is given by the product of the magnetic field density and the area element. More generally, magnetic flux is defined by a scalar product of the magnetic field density and the area element vector. ...

| magnet therapy |
Magnet therapy, or magnetic therapy, is a pseudoscientific form of alternative medicine based on the concept that certain medical disorders can be effectively treated by exposure to magnetic fields. Some believe that magnetic fields emanating from permanent magnets placed close to the body can cause bones to heal faster, relieve pain, and perform other forms of healing to the body. It is most commonly recommended by practitioners as a cure for joint disorders and back problems. ...

| magnetic resonance imaging |
MRI. A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. MRI makes better images of organs and soft tissue than other scanning techniques, such as CT or x-ray. MRI is especially useful for imaging the brain, spine, the soft tissue of joints, and the inside of bones. Also called nuclear magnetic resonance imaging.
