1
A measure of the number of magnetic field lines passing a region of space per unit area - magnetic flux per unit area
2
A measure of the number of magnetic field lines passing through a region of space (product of Flux Density and Area, when the field is perpendicular to the area)
3
The product of the magnetic flux and the number of turns on a coil through which a field passes
4
Field Strength, B (Tesla, T) × Area, A (metres², m²) × Cos(Angle between the field lines and the normal of the surface)
5
Magnetic Flux, ϕ (Webers, Wb) × Number of Coils in the Wire, N , Magnetic Field Strength, B (T) × Area, A (m²) × Number of Coils, N × cosθ, where θ is the angle between the coil and the field lines
6
We know that the field is uniform and will move in the same direction as the spring, and that the alternating current will vary the flux density and therefore, the flux linkage, This will induce an EMF in the coil which is detected by an oscilloscope , The amplitude of the line produced on the oscilloscope is equal to the magnitude of the induced EMF, Rotating the coil by a number of degrees changes the induced EMF , This allows a graph of EMF against the angle to be drawn, showing the relationship between flux linkage and the angle between the normal to the coil and the field
