Magnetic Flux Density Units Explained
Tesla (T)
The SI unit of magnetic flux density, defined as the magnetic flux per unit area. 1 T = 1 weber/square meter = 10,000 gauss. Named after physicist Nikola Tesla.
Common uses: MRI machines, electromagnet design, transformer specifications, magnetic sensor calibration, and particle accelerator design.
Gauss (G)
A CGS (centimeter-gram-second) unit of magnetic flux density. 1 G = 10⁻⁴ T = 0.0001 tesla. Named after mathematician and physicist Carl Friedrich Gauss.
Historical context: Still widely used in magnetism research, materials science, and geophysics. The Earth's magnetic field is approximately 0.3-0.6 gauss.
Weber per Square Meter (Wb/m²)
The fundamental SI definition of magnetic flux density. 1 Wb/m² = 1 Tesla. Represents the amount of magnetic flux per unit area perpendicular to the magnetic field.
Application: Direct calculation from magnetic flux and cross-sectional area, fundamental definition in electromagnetic theory.
Maxwell per Square Centimeter
A CGS unit of magnetic flux density. 1 Mx/cm² = 10⁻⁴ T = 1 gauss. Represents magnetic flux per unit area in CGS units.
Application: Magnetic material testing, hysteresis measurements, and magnetization curve characterization.
Gamma (γ)
A unit of magnetic flux density equal to 1 γ = 10⁻⁹ T = 1 nanotesla. Extremely small unit used for measuring weak magnetic fields.
Application: Geomagnetic surveys, magnetic anomaly detection, biomagnetics research, and magnetoencephalography (MEG) measurements.
Weber per Square Centimeter (Wb/cm²)
A mixed SI/CGS unit. 1 Wb/cm² = 10⁴ T = 100 million gauss. Represents magnetic flux per small unit area.
Application: Magnetic core saturation measurements and high-field magnet specifications.
Line per Square Centimeter
A CGS unit where 1 line/cm² = 1 maxwell/cm² = 1 gauss. Historical unit from CGS systems.
Application: Found in older literature and vintage equipment specifications, largely replaced by gauss and tesla.
Magnetic Flux Density Applications & Context
- Earth's magnetic field: Approximately 25-65 microtesla (250-650 milligauss)
- Permanent magnets: Typically 0.1-0.5 tesla at the surface
- MRI machines: Operate at 1.5, 3, or 7 tesla for clinical use
- Electromagnets: Can produce fields up to several tesla depending on design
- Superconducting magnets: Can achieve fields exceeding 20 tesla
- Ferromagnetic saturation: Most iron-based materials saturate around 2 tesla
- Hall effect sensors: Can detect fields as small as 1 milligauss to several tesla
