1. If the magnetic field is not uniform across a surface (its magnitude and direction change depending on where it crosses the surface) take the dot product of the magnetic field

I assume you mean flux density, In which case the formula is flux per m. 2. or (Wb)/m. 2. This unit is known as the. Tesla. (T) Therefore: (T)Wb)/(m. 2. hope this helps. sinewave.

The flux, Φ, through the area, A, due to field B is given by: Φ = BA. Φ = (100x10⁻⁶ T) x (0.02 m²) = 2x10⁻⁶ Tm². The more usual unit
