Describe the differences and similarities between an electromotor and a generator.

Differences:

An electrical motor converts electrical energy into mechanical energy,where as a generator converts mechanical energy into electrical energy.

The principle of a electric motor if there is a change of the magnetic field across a conductor  electrons are forced to move in a direction perpendicular to the direction of the magnetic field,where as in a generator if a charge is moving in a magnetic field, a force acts on the charge in a direction perpendicular to both the velocity of the charge and the magnetic field.

similarities:

Both electric motor and generator work on the magnetic effects of electric current.

Both have the armatures to rotate the loop.

which three statements are true about all alloys?
