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 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 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 North Pole: (1) The point where the Earth's surface intersects the axis of the dipole that best approximates the Earth's field. (2) The point where the Earth's magnetic field dips vertically downward.

Magnetic Inclination: The vertical angular difference between a horizontal plane and the orientation of Earth's magnetic field.

Magnetic North: The direction that a compass points. The location where Earth's magnetic field dips vertically into the Earth.

Magnetic Reversal: A change in the polarity of Earth's magnetic field in which the north magnetic pole becomes the south magnetic pole and vice versa. Also known as geomagnetic reversal or polarity reversal. E . . . View Full Definition

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.

Rotating Magnetic Field: The force created by the stator once power is applied to it that causes the rotor to turn.
