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 .
Measure for the strength of the magnetic field tesla (T = Wb/m 2) M T −2 I −1: pseudovector field Magnetic moment (or magnetic dipole moment) m: The component of magnetic strength and orientation that can be represented by an equivalent magnetic dipole: N⋅m/T L 2 I: vector Magnetization: M: Amount of magnetic moment per unit volume A/m L ...
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]
The oersted (Oe) is a unit of magnetic field strength equal to 1 dyn 1/2 ⋅cm −1, corresponding to ~ 79.577 47 A/m. The maxwell (Mx) is a unit of magnetic flux, corresponding to 10 nWb. [4] The gauss (G) is a unit of magnetic flux density, corresponding to 100 μT. [4]
The conversion factor is 10 8 maxwell per weber, since flux is the integral of field over an area, area having the units of the square of distance, thus 10 4 G/T (magnetic field conversion factor) times the square of 10 2 cm/m (linear distance conversion factor). 10 8 Mx/Wb = 10 4 G/T × (10 2 cm/m) 2.
Since the SI unit of magnetic moment is A⋅m 2, the SI unit of magnetization M is ampere per meter, identical to that of the H-field. The magnetization M field of a region points in the direction of the average magnetic dipole moment in that region. Magnetization field lines, therefore, begin near the magnetic south pole and ends near the ...
H is the magnetic field strength, also with the unit amperes per meter. χ v is therefore a dimensionless quantity . Using SI units , the magnetic induction B is related to H by the relationship
