Yes, they are permanent magnet DC motors. They run on DC and have been here for decades. The idea of a motor powered by magnets has been also with us for generations now. These are called perpetual motion devices. Motors will always need energy to run. They can not derive their energy from a magnet unless it consumes that magnet.

What is formed around both magnets in a motor?
A magnetic field.
Is radon magnetic?
No, radon is not magnetic. It is a radioactive gas and does not possess any magnetic properties.
What is galvanometer magnetic force and motor effect?
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
List of steps in which an electric motor changes electrical energy to kinetic energy?
Briefly: 1. Current flows through the wires in the Stator and the Rotor. 2. A magnetic field is generated in the Stator and the Rotor, caused by the Current Flow. 3. Because of the design of the "Wire Windings" of the Stator and Rotor, there Magnetic Fields are OPPOSITE each other, and REPEL each other. 4. If the Magnetic Fields are strong enough to overcome FRICTION (and any LOAD attached to the Motor), the Rotor begins to turn. 5. The Speed (RPM) of the Motor is either regulated by its design, or the LOAD.
What is the name of something that is not magnetic?
Try "non-magnetic". Also, since most magnetic materials contain Iron, then any non-ferrous metals are non-magnetic.
How do you make a magnetic motor?
Magnet->Electricity->Motor
What are examples of magnetical-magnetical?
Iron cobalt, nickel and their alloys are magnetic; magnetic bars for stirrers, magnetic bars for maximum-minimum thermometers, magnetic souvenirs, etc. are examples of magnets.
Why motor need pole?
electric and magnetic go hand in hand. One needed to produce other. Motor no magnetic pole, motor no work.
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.
Is a telephone magnetic?
yes it has a motor
What parts of a car are magnetic?
Starter, alternator, any part with an electric motor, because they use magnets to operate.
What energy convertions happen in an electric motor?
Electrical into magnetic, and then magnetic into mechanical.
Does amperage matter in induction motors?
Of course current matters! If you didn't have a current, then you wouldn't have a magnetic field; without a magnetic field, you wouldn't get any torque, and the motor wouldn't work!
Is there any rotating magnetic field in dc motors?
yeah ,if we consider a 3 phase dc motor ,the rotating magnetic field is produced by rotating the permanent magnet with a constant speed.
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
Who invented the electro magnetic motor?
the electromagnetic motor was invented by Nikola Tesla
Why does the wire on an electric motor have to be coiled?
To form the magnetic field that rotates the motor. :)
