tesla square meter [T*m^2] Unit Converter

Definition of tesla square meter [T*m^2] unit

A tesla square meter (T·m²) is the SI unit of magnetic flux. It equals one weber (Wb) and describes the flux produced when a one-tesla magnetic field is perpendicular to an area of one square meter.

History of tesla square meter [T*m^2] unit

The tesla square meter emerged from efforts to express electromagnetic quantities coherently. The tesla was named in 1960 for Nikola Tesla, whose work advanced alternating-current power and electromagnetic technology. Magnetic flux had earlier been measured using the maxwell in the centimeter-gram-second system. The weber, named for German physicist Wilhelm Eduard Weber, became the SI derived unit for magnetic flux when the modern SI was established in 1960. Since one weber equals one tesla times one square meter, T·m² provides the unit’s direct dimensional expression and remains an accepted equivalent notation.

Applications of tesla square meter [T*m^2] unit

Today, tesla square meters are used to quantify magnetic flux in electric motors, generators, transformers, inductors, and magnetic sensors. Engineers use the unit when calculating flux linkage, designing cores, and evaluating permanent magnets or superconducting magnets. Magnetic resonance imaging systems, particle accelerators, and laboratory instruments also report field-area products in webers or equivalent T·m².
