(unit of magnetic flux density)

A Tesla (T) is the SI unit of Magnetic Field Strength or Magnetic Flux Density (B). It is defined as a Weber per square meter. A particle carrying a charge of one Coulomb passing through a field of one Tesla at a speed of one meter per second experiences a force of one Newton.

1 tesla equals 10,000 Gauss, the CGS unit measuring the same physical property.
