Calculation of Total Magnetic Flux
If the Magnetic Field is non-uniform, with various magnitudes and directions at different areas of the surface, the total magnetic flux across the surface may be calculated as the product of all such area elements and their respective magnetic fields.
Mathematically,
ϕB = B1.dA1 + B2.dA2 + B3.dA3 + … = ∑all Bi.dAi
Magnetic Flux is Vetor or Scalar
The Magnetic Flux is a Scalar quantity, as shown by the equation above. Weber (Wb) or Tesla Meter Squared is its SI unit (Tm2).
Measurement of Magnetic Flux
A Magnetometer may be used to measure the Magnetic Flux. Assume a magnetometer probe is moved over a 0.9 m2 region near a huge sheet of magnetic material and shows a constant reading of 10 mT. The magnetic flux through that area is then computed using the formula (10 × 10−3 T) (0.9 m2) = 0.0090 Wb. It would be essential to find the average measurement in the event of shifting magnetic field readings across a large region. The Weber (Wb) or Tesla Meter Squared (Tm2) unit of Magnetic Flux is named after German scientist Wilhelm Weber.
Magnetic Flux
Magnetic Flux is defined as the surface integral of the normal component of the Magnetic Field(B) propagating through that surface. It is indicated by φ or φB. Its SI unit is Weber(Wb). The study of Magnetic Flux is done in Electromagnetism which is a branch of physics that deals with the relation between Electric Current and Magnetic Field.
