It Can Be Shown That . . .
If the coil is wound such that the flux through each turn is the same (if the windings are parallel), the induced voltage is given by:
(1") ![](graphics/vc_3Z1.gif)
- where:
- V is the induced voltage and
- N is the number of turns.
Equation 1" can be rewritten as:
(2") ![](graphics/vc_3Z2.gif)
- where:
- B is the strength of the magnetic field and
- A is the area of the circuit exposed to the magnetic field.
From Equation 2" after substituting Lx for the area A:
(4) ![](graphics/vc_3Z3.gif)
- where:
- Lx is the area of the coil that is exposed to the magnetic field,
- x is the height of coils, and
- dx/dt is the velocity of the coil movement.
