Magnetic Field Strength Converter
Magnetic field strength (H) is the magnetising field a current produces, as distinct from the resulting flux density (B). The SI unit is the ampere per meter. Permanent-magnet data sheets still quote coercivity in oersteds, where one oersted is about 79.6 A/m.
6 units supported Base unit ampere per meter (A/m)
Multiply the number of amperes per meter by 0.001 to get kiloamperes per meter. How this is calculated
About magnetic field strength conversion
Magnetic Field Strength conversion is commonly needed when magnet specification, coil design, and magnetic circuit analysis. Field strength H (amperes per metre) is what the current creates; flux density B (tesla) is what the material produces in response.
