Magnetic field, field strength, and flux density

Magnetic field, field strength, and flux density In physics, there are two different attributes of a magnetic field: The "magnetic field strength" Usually given the symbol H Measured in amps per metre (A/m) The "magnetic flux density" Usually given the symbol B Measured in teslas (or microteslas or gauss) In electromagnetism theory, it is absolutely clear that these are differentThe flux can be distributed widely, producing and extended and weak field, or it could be very concentrated, resulting in a strong compact field There are two measurable parameters that are effected by the flux distribution, these are field strength and flux density Field strength A larger mmf will naturally produce a stronger field WithMagnetic Field Strength | Flux Density | MagnetismMagnetic Flux Density Formula: The magnetic flux per unit area is called magnetic flux density in Tesla (webers per metre2) and it is a vector quantity B = Φ/A Where: B = Magnetic Flux Density Φ = Magnetic Flux A = Area Magnetic Field Intensity Formula: Magnetic field strength or magnetic field intensity can be calculated by using theElectric & Magnetic Flux, Density & Field Intensity Formulas
