   The magnetic field of a small [note 6] straight magnet is proportional to the magnet's strength (called its magnetic dipole moment m). The equations are non-trivial and depend on the distance from the magnet and the orientation of the magnet.

   www.techtarget.com › whatis › definition

   Magnetic field strength is a measure of the intensity of a magnetic field in a given area of that field. Represented as H, magnetic field strength is typically measured in amperes per meter (A/m), as defined by the International System of Units (SI).

   Magnetic field strength, often represented by the symbol 'H', is a measure of the intensity of a magnetic field produced by an electric current or a magnet. It describes how strong the magnetic effect is in a given area and is critical for understanding how magnetic fields interact with materials, such as currents and magnetic forces acting on ...
