THE TESLA
The standard unit of magnetic flux density is the tesla, symbolized T. One tesla is equivalent to one weber per meter squared (1 Wb/m2 or Wb . m-2) when the flux is perpendicular to the surface under consideration. Sometimes magnetic flux density is spoken of in terms of the number of “lines of flux” per unit cross-sectional area; this is an imprecise terminology unless we are told exactly how much magnetic flux is represented by a line.
