Magnetism Converters

About Magnetism Converters

Magnetism underlies everything from electric motors and generators to MRI machines and data storage — and describing it precisely requires converting between several distinct physical quantities, each with its own SI and CGS units. UnitConvertersLab's Magnetism Converters bring together four specialized calculators covering the magnetic quantities physicists, electrical engineers, and magnetics researchers work with every day: magnetic flux density, magnetic field strength, magnetic flux, and magnetomotive force.

Magnetic Flux Density (the B field) measures how concentrated a magnetic field is at a given point, in tesla (T) in SI units or gauss (G) in the older CGS system — the quantity printed on MRI machine specifications (1.5T, 3T scanners) and used to rate magnets and electric motor designs. Magnetic Field Strength (the H field) measures the magnetizing force that produces that flux density, in amperes/meter or the CGS oersted, and is distinct from flux density because it doesn't depend on the material being magnetized.

Magnetic Flux measures the total amount of magnetic field passing through a given area, in weber (Wb) or the CGS maxwell — the quantity that, when it changes over time, induces the electric current at the heart of generators, transformers, and inductors (via Faraday's law of induction). Magnetomotive Force is the magnetic analogue of electromotive force (voltage) — the "driving force" that pushes magnetic flux through a magnetic circuit, measured in ampere-turns or the CGS gilbert, essential for designing transformers, relays, and electromagnets.

Every converter on this page works the same way: pick a "from" unit and a "to" unit from the dropdown lists, type in a value, and get an instantly calculated, high-precision result — up to 12 significant digits — with no account required and nothing to install. Each tool is optimized for desktop and mobile alike, so you can pull up a quick conversion in the lab, the classroom, or on the shop floor.

These four categories were chosen because magnetics literature and equipment specifications routinely mix SI units (tesla, weber, ampere/meter) with older CGS units (gauss, maxwell, oersted, gilbert) that remain common in certain industries and older reference materials — getting the conversion factor right (often a power of 10 or a less obvious ratio) is essential to avoid serious calculation errors in electromagnet, motor, and transformer design.
