Comprehensive Formulas & Variable Breakdown
1. Magnetic Flux (Φ)
Magnetic Flux is a measurement of the total magnetic field (represented by field lines)
passing through a specific area [cite: 7, 9]. Think of it as the "volume" or "concentration"
of magnetic flow [cite: 9]. If you have a stronger magnet or a larger loop of wire, you get
more flux [cite: 9].
Φ = B · A · cos(θ)
Variable Definitions:
Φ (Magnetic Flux): The total flow of magnetism through the area. Webers (Wb)
[cite: 7, 9].
B (Magnetic Flux Density): The intensity of the magnetic field. Tesla (T) [cite: 7,
9].
A (Area): The size of the surface the field lines pass through. m² [cite: 7, 9].
θ (Theta): The angle measured between the Normal and the magnetic field lines
[cite: 7, 9].
The "Normal" Line Secret: Always draw a line 90 degrees to the surface [cite: 8, 9].
The angle θ in your formula is the space between that line and the magnetic field
