A method of supporting and transporting objects and vehicles by using a magnetic field to counterbalance the gravitational pull.

(modern) B-field. / (dated) H-field.

(geography) At a given point, the direction in which the magnetic North Pole of the Earth lies.

The recording of a signal; sound or image, on a magnetizable vessel or medium for storage, and retrieval purposes.

(physics) a measure of the magnetisation of a material in a magnetic field; symbol μ. Materials with values less than 1 are diamagnetic those above are paramagnetic.

(physics) a thermometer whose operation is based upon Curie's law; typically used to measure temperatures below 1 K

Any of several reversals in the polarity of the Earth's magnetic field (such that a compass points South) that have happened over geologic time.

(physics) a measure of the magnetization of a material per unit of applied magnetic field

(physics) A hypothetical particle having an isolated north or south pole; the magnetic equivalent of an isolated electric charge.

(physics) the state of being a north pole or south pole; the magnetic equivalent of electric charge
