Glossary for Electromagnetism
Add at least two words to the glossary that you have learned in Electromagnetism. It doesn't matter if yours is another definition of a word that is already in the glossary.

Aluminium, nickel and cobalt alloy
Like a fridge magnet, scattered magnetic particals, weak magnet, will not work with other magnets.
Is not a magnetic material, like air.
Cumulative Compounded machines have the series field and the shunt field assisting each other.
A material that is repelled by magnetism. This is due to it having a weak opposing polarity
circular motion of current
Electro technology first word magnetism first word
Materials (eg iron) that are strongly attracted to both poles of a magnet.
Ferromagnetic materials are strongly attracted to both poles of a magnet.
The flux per unit of an electric, luminous or magnetic field.
The unit of Inductance
The delay between the change to a system and the resulting output.
The effect that inductors have to changing current.
An inductor is a coil of wire.
Voltage drop due to current and resistance.
A materials opposition to being magnetised.
Mechanical force is exerted. on a current-carrying conductor in a magnetic field
Mutual Inductance is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil.
A permanent magnet made from an alloy of neodymium , iron and boron.
An object which is slightly attracted by a magnetic field
Paramagnetic materials are weakly attracted to both poles of a magnet.
The ease with which a magnetic material can be magnetised.
At 90 degrees
The direction of a magnetic or electric field.
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.)
The thing that spins the generator. I could be wind.
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:
Reluctance is the magnetic equivalent to resistance.
This is the ability of a ferromagnetic materiap to retain magnetic flux
Has just about as mach as it can easily take. Applying more force will result in minimal additional field.
The unit of Flux Density
The Symbol is B
Measure of change in voltage magnitude between sending and recieiving end.
Voltage Regulation is the difference between the no load voltage and the full load voltage expressed as a percentage of the full load voltage.
