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.

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 does an electromagnet do when it is connected with wires and a motor?
When an electromagnet is connected to wires and a motor, the electromagnet generates a magnetic field when current flows through the wires. This magnetic field interacts with other magnetic fields in the motor, causing the motor to either spin or generate motion depending on the design and configuration.
Can an electric motor work without a magnet?
No, an electric motor requires a magnetic field to function. The interaction between the magnetic field and electric current generates the force that drives the motor's motion. Without a magnet, the motor would not be able to convert electrical energy into mechanical energy.
What is formed around both magnets in a motor?
A magnetic field.
What kind of motor operates on the principle that like magnetic poles repel?
A linear induction motor operates on the principle that like magnetic poles repel. This type of motor uses electromagnetic fields to generate motion by inducing currents in a conductor.
Why does the wire on an electric motor have to be coiled?
The wire in an electric motor is coiled to create a magnetic field when an electric current flows through it. This magnetic field interacts with other magnetic fields in the motor, causing the motor to rotate. Coiling the wire helps increase the strength of the magnetic field and improves the motor's efficiency.
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.
How do you make a magnetic motor?
Magnet->Electricity->Motor
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.
What parts of a car are magnetic?
Starter, alternator, any part with an electric motor, because they use magnets to operate.
Is a telephone magnetic?
yes it has a motor

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.
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!
What energy convertions happen in an electric motor?
In an electric motor, electrical energy is converted into mechanical energy. This conversion is achieved by the interaction of the magnetic fields generated by the flow of electric current in the motor's coils, causing the motor to rotate and produce mechanical work.
