## Magnetic field, field strength, and flux density

Sometimes, people will be very precise and talk about either the magnetic flux density or the magnetic field strength But actually "magnetic field" is perfectly valid as a description of either both the magnetic flux density and the magnetic field strength are examples of a magnetic field And just using "magnetic field" is a lot simpler

## Magnetic Hysteresis Loop including the BH Curve

DefinitionUsesExampleCriticismsAdvantagesMechanismIntroductionApplicationsTreatmentEffectsPreviously, the relative permeability, symbol μr was defined as the ratio of the absolute permeability μ and the permeability of free space μo (a vacuum) and this was given as a constant However, the relationship between the flux density, B and the magnetic field strength, H can be defined by the fact that the relative permeability, μr is not a constant but a function of the magnetic field intensity thereby giving magnetic flux density as: B =electronicstutorialsws## What is the relation between magnetic flux density (B) and

Magnetic field strength or field intensity (H) is the amount of magnetising force Magnetic flux density (B) is the amount of magnetic force induced on the given body due to the magnetising force H The relation between B and H is, B = μH Where, μ is the relative permeability Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself

## FIELD INTENSITY and POWER DENSITY T

Field intensity (field strength) is a general term that usually means the magnitude of the electric field vector , commonly expressed in volts per meter At frequencies above 100 MHZ, and particularly above one GHz, power density (P D ) terminology is more often used than field strength Power density and field intensity are related by equation
