Does a washing machine need a magnet to operate?
The answer is both yes and no.It actually depends on the kind of washing machine in question.The problem is the motion.A washing machine need some kind of an engine or motor in order to move the cloths back and forth. This can of course be done manually.If we rule out manual washing machines, and also only count in electrical ones then these can be made in two different ways.The motor causing the tumbling or the motion in the washing machine can be made with both permanent magnets like NeoDym, or with purely electrical pulses creating strong electromagnetic fields.Most motors in washing machines made today are made without magnets. It is cheaper to make purely electrical motors where the electricity provides the magnetic fields needed. By electronically rotate the magnetic field around the axis, this will force the motion of the motor. It would use less electricity to make the motors with NeoDym magnets but it would also cost more to produce.As a conclusion: We can not make an electrical washing machine that operate without magnetic fields, but magnetic fields does not have to be made by magnets.
Is voltage the force that causes motion?
no, the force that causes motion is called inertia, while yes voltage is needed to make things work, it is also a unit of measurement for electricity.
Can the chair make a motion in a meeting?
can the chairman make a motion?
Can you make sentence of motion?
The motion of a boat often make people very sick.
What energy conversion happens in an fan?
fan converts electric energy into magnetic and further mechanical energy
Does Smith Motors make car or air-conditioning motors?
The A.O. Smith company is a top supplier of electrical products for automobiles. They manufacture hermetic motors for air conditioning that are used in automobiles.
Does three motors make enough energy to run a light bulb?
Electrical motors use electrical energy, they don't produce it. Generators produce electricity. Also, since they come in very different sizes, you would have to take a look at the generator's electrical specifications, specifically its power (or multiply voltage x current), and compare to those of the light-bulb.

What can you can use with power?
Your question doesn't make much sense to me. Power of different types is used for a vast range of things. Electrical-motors, heaters, computers, lighting, air conditioning, etc, etc. Mechanical-vehicles, trains, ships, aircraft, etc, etc. P.S the person who questioned this dosent make sense
How does a car move?
Cars have either internal combustion engines, or electric motors (or both) which make them move. This is a fairly large subject which we cannot fully deal with in the form of an answer on this site. Suffice to say, by the use of ingenious and intricate machinery, the chemical energy stored in gasoline, or the electrical energy stored in a battery, can be converted into forward motion of a car.
How does a car motor work?
A car motor works because it has gas and a spark, the two things that make most motors work.
Is it true that a turbine turns kinetic energy to electrical energy?
No. A turbine turns linear motion of a working fluid (which can be a liquid or gas) into rotational motion. No electricity need be involved.You can hook a turbine to a generator and use the rotational motion produced by the turbine to make electricity. But the turbine itself does not do this.
Is voltage the force that causes motion?
no, the force that causes motion is called inertia, while yes voltage is needed to make things work, it is also a unit of measurement for electricity.
How does an electric side mirror work?
Electric side mirrors work through the use of small servo motors. They are powered by the vehicle's electrical system and make small movements based on the driver's input.
Can the chair make a motion in a meeting?
can the chairman make a motion?
What are some forces that can make things move?
Force accelerates things. If the thing isn't already moving, then acceleration can result in motion. Any force works.
What are the uses for permanent magnets?
to make motors
