What part of motor makes the current in the coil reverse every half turn so that motor spins continuously?

The direction of the current flowing through it must be changed after every half rotation. Otherwise, when the north pole of the coil comes near the south pole of the magnet, there will be attraction between them and the coil will stop rotating.

The electric force that makes current flow in a circuit is related to the what?
The electric force that makes current flow in a circuit is related to the resistance.

Rephrase your question so that it makes sense.
What component that makes it more difficult for current to flow?
IF there is a Resistor
What The property of a coil that makes it resist changes in current is called?
Inductance
What is the difference between current and voltage commutation?
Voltage commutation: This is possible in ac circuits...The thyristor gets turned off by reverse bias (negative half cycle) voltage applied across it. This is also called line commutation. Current Commutation: This is possible in dc circuits ...This type of commutation makes use of auxiliary circuit which contains inductor,capacitor,diode and even a thyristor(auxiliary). This is called Forced commutation.
Is electric current flows reversible?
Of course. If you take the batteries out of a flashlight and put them back in pointingthe other way, the current goes through the bulb in the opposite direction.It's so easy to reverse the flow of electric current that . . .-- the current coming out of a household electric socket reverses 120 times every second,-- the current in the antenna of your FM radio reverses roughly 200 million times every second-- the current in the antenna of your cellphone reverses almost 2 billion times every second,-- the current in the magnetron that makes the microwaves that heat your leftover meat loafreverses 4.9 billion times every second.
What makes the heart such an efficient self-regulating pump?
The structure of the heart is what makes it an efficient pump. It works continuously without tiring, and it receives electric signals every second and pumps blood nonstop.
Explain Why it is important that the current in the coil of a motor changes direction every time the coil makes a half revulotion?
due to commutation the current in the coil reverses
Does man's body continuously produces semen and sperms or they get produced at the time of ejeculation?
A man continuously makes sperm for all of his life.
What makes a car go backwards?
Reverse
How are reverse fault created?
When rocks move in to each other. When two plates are constantly hitting each other, they form a convergent boundary, which forms a reverse fault. The Compression between these plates (or push) makes one slide above the other. If this happens continuously, one will be above the other, resting on it. This creates a hanging and foot wall.
The business of a business is a business?
The business of a business is ECONOMICS itself. What makes ECONOMY continuously flow is business. What makes countries innovate is business. What generate jobs is business. What creates improvement projects are business. Almost every aspect of business is primarily targeted in terms of ECONOMIC flow.
What are the uses of current electricity?
The easiest way to answer your question is to point out that every device you own or use, which you plug into the wall or which contains a battery, makes available to you some use of electrical current. Whatever you use each of those devices for is a use of current electricity.
Operation of ttl gate with totem-pole output?
For the working of TTL nand with totempole When both inputs are LOW The emitter base junctions at A and B gets forward biased, base -collector junction gets reverse biased for Q1.So maximum current flows through forward biased junction. As base -collector junction of Q1 gets reverse-biased, base current through the Q2 is ZERO, which makes Q2 OFF. As Q2 is in OFF state, base current through Q4 is ZERO, which makes Q4 OFF.As Q2 is in OFF state the current through R2 flows through base of Q3 which makes Q3 and diode D to ON.As Q4 is in OFF state the current flows through the load, which make output to go HIGH state
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
If we are losing heat to the air why does our temperature not decrease?
Your body continuously makes energy that keeps your body warm.
What is saminila?
saminila is a disease that makes you throw up continuously. It can be carried by, raw foods, reptiles, and amphibians.
