The most practical form would be that which more nearly conforms to the steady running produced by a steam turbine or electric motor.
These three digits, as will be noticed, are all at right angles to each other, and this relation is the best for inducing the strongest current in a dynamo or the most energetic movement of the conductor in an electric motor.
Similarly in an electric motor, the stronger the current and magnetic field the faster will the conductor move.

An electric motorforms an integral part of many machine tools in numerous modern machine shops.
It is also by means of these electro-magnets that man can get us to turn an electric motor, and so on.
An electric motor is practically the same as a dynamo, but instead of turning its coil round in order to produce an electric current, we pass a current into the coil and it moves round.
This current may be conducted to a distant tramway car, and, by sending the current through an electric motor, mechanical motion is produced and the car propelled along.

Another reason is that an electric motor can, if called upon, develop an amount of power two or three times greater than its full-rated capacity without injury, providing the strain is not maintained too long.
An electric motor can be turned into an electric generator by simply reversing the direction in which the armature rotates--that is, any electric machine is either a generator or a motor.
