P

Paramagnetic Materials

Paramagnetic materials are weakly attracted to both poles of a magnet.


Permeability

The ease with which a magnetic material can be magnetised.


Perpendicular

At 90 degrees


Polarity

The direction of a magnetic or electric field.


Primary

The first coil in a transformer. In other words the one connected to the power sauce.
(do you like what I did there. I made a funny joke about sauce when it should have been source. I'm bloody hilarious aren't I.)

Prime Mover

The thing that spins the generator. I could be wind. 


R

Regulation

The measure of how well a power generator maintains constant voltage over a range of load currents is called voltage regulation. It can be calculated from the following formula:

R e g percent sign equals 100 asterisk times fraction numerator V subscript n o space l o a d end subscript space minus space V subscript f u l l space l o a d end subscript over denominator V subscript f u l l space l o a d end subscript end fraction


Reluctance

Reluctance is the magnetic equivalent to resistance.


Residual

left over


Retentivity

This is the ability of a ferromagnetic materiap to retain magnetic flux
