# Relationship between ampere turns and flux density calculator

### Converting Magnetic Field Strengths - Ampere-Turns to Tesla : askscience

Calculate the amount of magnetic flux (Φ) in a piece of iron with a reluctance (ℜ) of 55 amp-turns per weber and an applied MMF (F) of amp-turns. Explain the difference between relative permeability (µr) and absolute permeability (µ). How do density (B) and field intensity (H, otherwise known as magnetizing force). Magnetic Field Unit conversion Tool: Unit conversion of magnetic flux density The relation between Magnetic strength H and flux density B can be defined by B = μH. field strength is defined by the unit of Oe・A/m (Oersted・Ampere/meter). It is measured in ampere-turns, the electrical current in the coil, measured in we had 5, turns of wire in our coil, we would have 5, times the flux density, .
