Magnetic flux

Definition: In a uniform magnetic field, the product of magnetic induction intensity B and a certain area S perpendicular to the direction of the magnetic field is called the magnetic flux passing through this area“ Φ” express.

Therefore, the magnetic flux calculation formula is:

Magnetic flux calculation formula

The specific meanings represented in the above formulas are:

B: Represents the magnetic induction, in T

S: Is the area perpendicular to the direction of the magnetic field line, in m2

Φ： Is the magnetic flux passing through the S area, in Wb

Magnetic flux unit: magnetic flux identifier Φ The SI unit is Weber, often represented by the symbol Wb. In electric power engineering calculation, Maxwell is also often used as the unit, which is referred to as "Mai". The conversion relationship between Weber and Maxwell is as follows:

1 Maxwell (Mx)=1 Gauss (Gs) × Cm2=10-8 Weber (Wb)
