  2. Tesla (unit) - Wikipedia

    en.wikipedia.org/wiki/Tesla_(unit)

    The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre. The unit was announced during the General Conference on Weights and Measures in 1960 and is named [1] in honour of Serbian-American electrical and ...

    Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance (⁠ 1 / distance 3 ⁠) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]

    Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

  7. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    In the International System of Units, the unit of B, magnetic flux density, is the tesla (in SI base units: kilogram per second squared per ampere), [5]: 21 which is equivalent to newton per meter per ampere. The unit of H, magnetic field strength, is ampere per meter (A/m).

    tesla meter (T⋅m) area: square meter (m 2) amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2) magnetic flux density also called the magnetic field density or magnetic induction tesla (T), or equivalently, weber per square meter (Wb/m 2)

  9. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    The SI units of B are volt-seconds per square meter, a ratio equivalent to one tesla. The concept of permeability arises since in many materials (and in vacuum), there is a simple relationship between H and B at any location or time, in that the two fields are precisely proportional to each other: [2] =,
