3 Terms and definitions

The following terms and definitions apply to this document:

3:1

Magnetic field

A special form of matter generated by the space around magnets, electric currents, and moving electric charges, which transmits the magnetic field between real objects:

Note: The field strength that usually constitutes the magnetic moment of spacecraft products includes residual magnetic field, stray magnetic field, induced magnetic field and eddy current magnetic field:

3:2

Magnetic moment

A physical property of magnetic objects, which is a physical quantity that describes the magnetism of magnets and current-carrying coils:

Note: The magnetic moment corresponding to the field intensity source includes the residual magnetic moment, stray magnetic moment, induced magnetic moment and eddy current magnetic moment:

3:3

The magnetic field that remains when the spacecraft is not operating after the external magnetic field is eliminated:

3:4

The magnetic moment corresponding to the spacecraft's residual magnetic field:

3:5

When the spacecraft is powered on, the magnetic field is caused by the electric current:

3:6

The magnetic moment corresponding to the stray magnetic field of the spacecraft:

3:7

The magnetic field induced by the soft magnetic materials of the spacecraft under the influence of internal and external magnetic field factors:

3:8

The magnetic moment corresponding to the magnetic field sensed by the spacecraft:
