My motor works be ground of the fundamental laws of magnetism. The north gat of the magnet attracts the south pole of the magnet because they have opposite charges; poles of the same charge forget push each other. This attracting and yucky of the magnets is what allows the motor to run. Inside an galvanising motor, this attracting and repelling of the magnets allows rotational execution to occur.
In assembling this electrical motor, I actually created an electromagnet by wrapping many loops of wire to the motor shaft and the armature, suspending it in the middle of the field poles, and connecting it to a battery. The field poles takes on the habit of an electromagnet when an electric flow rate flows through the wire loops wrapped more or less the bottom piece. And when a current goes through the wire bankroll of the armature, it also becomes an electromagnet. The armature produces a reversing charismatic field while the magnetic field produced by the field poles remains stationary. There will be a half-turn of motion because of the way that magnets attract and repel one another, and then the field of the electromagnet will flip and cause the electromagnet to go through another half-turn rotation.
The purpose of the commutator is to reverse the electric current in the axial rotation each time the coil rotates through half a turn. When the field of the electromagnet flips right at the end of each half-turn rotation, the electric motor starts spinning freely. The current from the battery connects to the electric terminals of the motor; and these electric terminals feed electric power into the commutator through the encounteres, a pair of loose connectors that brush up (must be touching) against the commutator. When the commutator has been assembled into place, the coil will keep on rotating in the same direction if electricity flows through the circuit.
As seen in the first experiment, the magnetic field can be flipped just by flipping the battery over, which changes the...If you want to get a full essay, order it on our website: Orderessay
