Eng ID Term Definition
3041
magnetic retentivity
The ability to retain MAGNETISM after removal of the mag­netizing force. Also called remanence.
3042
magnetic secular change
The temporal variation in the value of a MAGNETIC ELEMENT which occurs over a period of years.
3043
magnetic station
See STATION.
3044
magnetic storm

A distur­bance in the EARTH'S MAGNETIC FIELD, associated with abnormal solar activity, and capable of seriously affect­ing both radio and wire transmission.
3045
magnetic survey
See SURVEY.
3046
magnetic temporal variation
Any change in the EARTH'S MAGNETIC FIELD which is a function of time. Also refer­red to as temporal variation.
3047
magnetic variation
See VARIATION.
3048
magnetism
The ability to attract magnetic material, notably iron and steel.
3049
magnetism: induced
MAGNETISM acquired by a piece of magnetic material while it is in a MAGNETIC FIELD.
3050
magnetism: permanent
MAGNETISM which is retained for long periods without appreciable reduction, unless the MAGNET is subjected to a demagnetizing force. Because... more
MAGNETISM which is retained for long periods without appreciable reduction, unless the MAGNET is subjected to a demagnetizing force. Because of the slow dissipation of such MAGNETISM, it is sometimes called subpermanent magnetism.
3051
magnetism: residual
MAG­NETISM which remains after removal of the magnetizing force.
3052
magnetism: subpermanent
See MAGNETISM: PERMANENT.
3053
magnetism: temporary
MAGNETISM of craft which changes in amount with every change of HEADING. Also called transient magnetism.
3054
magnetism: terrestrial
See GEOMAGNETISM.
3055
magnetism: transient
See MAGNETISM: TEMPORARY.
3056
magnetization
The degree to which a body is magnetiz­ed. The MAGNETIC MOMENT per unit volume. Also called inten­sity of magnetization.
3057
magnetize
(v.t.). To produce magnetic properties. The opposite is DEMAGNETIZE.
3058
magnetogram
An analogue time record of the temporal variations in a MAGNETIC ELEMENT measured at a MAGNE­TIC OBSERVATORY.
3059
magnetograph
A MAGNETIC OBSERVATORY instrument consi­sting of one or more (usually 3) VARIOMETERS, one for each MAGNETIC ELEMENT recorded, and a recorder... more
A MAGNETIC OBSERVATORY instrument consi­sting of one or more (usually 3) VARIOMETERS, one for each MAGNETIC ELEMENT recorded, and a recorder.
3060
magnetometer
An instrument for measuring the intensi­ty and/or the direction of the EARTH'S MAGNETIC FIELD.
