### magnetic field strength Definition & Facts Britannica

Magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual

### Magnetic Field Intensity Definition Formula Electrical

Magnetic Field Intensity Unit Magnetic field intensity is also known as the magnetizing force which is measured is ampere-turns per meter (A-t/m). Of primary concern, however, is the magnetomotive force needed to establish a certain flux density, B in a unit length of the magnetic circuit.

### What is Magnetic field intensity? Electricalvoice

Apr 17, 2020· Magnetic field intensity is defined as the degree to which the magnetising field can magnetise a material. The magnetic field which magnetises a material placed in it is known as the magnetising field.Magnetic field intensity is denoted by ‘H‘ and also known as intensity of magnetising field or magnetising force.

### Earth's magnetic field Wikipedia

Intensity. The intensity of the field is often measured in gauss (G), but is generally reported in nanoteslas (nT), with 1 G = 100,000 nT.A nanotesla is also referred to as a gamma (γ). The tesla is the SI unit of the magnetic field, The Earth's field ranges between approximately 25,000 and 65,000 nT (0.25–0.65 G). By comparison, a strong refrigerator magnet has a field of about 10,000,000

### Magnetization & Magnetic Intensity Magnetic Properties

Magnetization, also termed as magnetic polarization, is a vector quantity that gives the measure of the density of permanent or induced dipole moment in a given magnetic material. As we know, magnetization results from the magnetic moment, which results from the motion of electrons in the atoms or the spin of electrons or the nuclei.
