What component is made of loops of wire that rotate in the magnetic field provided by the field poles and field coils?
the rotor coils in an electric motor
What is field coils?
field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.
What causes the axle to spin in an electric motor?
Switching the field voltage to the coils forces the magnets to move.
How is a motor used in the generation of electricity?
Motors turn rotors that rotate coils of wires over a magnetic field, which creates an electric current in the wire.
An electric motor turns because the electricity passing through its coils produces?
An electric motor turns because its coils are present between the poles of a strong magnet or electromagnet. Whenever a current passes through a wire in a magnetic field, the wire moves. The electromagnet and the copper coils are arranged in such a manner that when a current passes through the coil an armature linked to the coil rotates.
What are magnetic shading coils and what do they do in a magnetic motor Starter?
Shading coils provide a phase shift between the magnetic field of the rotor and stator, which is necessary to get the motor spinning.
Why does the wire on an electric motor have to be coiled?
To form the magnetic field that rotates the motor. :)
What is a not a part of an electric motor?
A field of wheat
Which device uses a rotating electric power source to produce a magnetic field?
well as the name mention production of magnetic field due to rotation. if we consider three identical coils axis physically by120* each and 3 phase supply given then their is the production of aleternating magentic field in each coil
What part of an electric fan makes a magnetic field?
a motor
Why is a motor needed in a circiut?
A motor is not needed in a circuit, a motor is an electrical load for the current to drive, but the circuit can perform with other types of load - such as a lamp, a transformer, a heating coil, or any electronic load. if you mean 'why does an electric motor need a circuit?' this is because the motor is an electrical device which has coils of wire to produce a magnetic field, without the circuit it cannot function.
Coils of wire wrapped around a ferromagnetic core make up a motor's?
Coils of wire wrapped around a ferromagnetic core make up a motor's armature. It carries an electrical current and rotates within a magnetic field.
