Magnet Boot: A rubber or plastic cover for the magnet housing for protection or appearance, mostly the latter.

Magnetic Quantum Number: Quantum number that labels different orbitals within a subshell. Mell can take on values from -ell to +ell. The number of orbitals in a subshell is the same as the number of possible mell values.

Magnetic Resonance Imaging (MRI): Medical imaging technique (like X-rays and ultrasound) allowing physicians to see images of tissues. It is often used to examine the brain or spine.

Magnetic Stratigraphy: The study and correlation of polarity epochs and events in the history of the Earth's magnetic field as contained in magnetic rocks.

Magnetic Poles: Either of the two points on the earth's surface where the magnetic meridians converge. They are not aligned with the geographical poles, but shift and do not lie exactly opposite of the other.

Magnetic Polarity: It is a fundamental principle of a winding that adjacent poles must be wound to give opposite magnetic polarity. This does not mean that the coils actually have to be wound in this direction . . . View Full Definition

Magnetic Flux Density: The measurement of magnetic flux, in units of Gauss, inside the air gap in which a voice coil of a speaker operates.

Magnetic Direction: Direction as indicated by a magnetic compass after correction for deviation but without correction for variation.
