Magnets are used in motors to create motion. Magnets have two kinds of polarity, positive (north) and negative (south). When two magnets of the same polarity are facing each other, they will be attracted to each other. Conversely, if the polarity of the the two magnets are opposites than they two magnets will be repulsed. This concept of rotational motion is what is occurring in a motor.

What is an object that attracts metal?
A magnet is an object that attracts metal due to its magnetic field. When a metal object comes in close proximity to a magnet, it is pulled towards the magnet due to the attractive force between the magnetic poles.
If you were given a magnet with unmarked poles how could you determine which pole was which?
You could use another magnet with marked poles to determine the poles of the unmarked magnet. By observing how the unmarked magnet interacts with the marked magnet, you can identify the north and south poles of the unmarked magnet based on attraction and repulsion.
How can you separate iron nails from copper tacks?
One way to separate iron nails from copper tacks is to use a magnet. The iron nails will be attracted to the magnet, allowing you to easily separate them from the copper tacks.
If you spilled a box of pins how could you pick them up quickly?
Use a magnet to quickly pick up the pins, as they are usually made of metal and will stick to the magnet. Alternatively, use a lint roller or sticky tape to easily lift the pins off the surface. Lastly, you can use a vacuum cleaner with a hose attachment to efficiently suck up the pins.
How could you separate iron and sulfur?
Iron and sulfur can be separated by using a magnet. Since iron is magnetic, you can use a magnet to attract and separate the iron from the sulfur.
How do you make a magnetic motor?

What machines use magnets?
Every machine with a motor has a magnet. If you plug it in, it has a magnet. If you put in batteries or recharge it, it has a magnet. An automatic pencil sharpener uses magnets. A computer printer uses magnets. A refrigerator motor uses magnets. An electric razor uses magnets. A fan uses magnets. Hair cutters use magnets. Nose clippers use magnets. Look around your room and see what else uses a motor.
Can you run a 24 volt dc motor with 24 volt ac power?
Not usually. But this depends on how the motor is made. So a permanent magnet motor is usually a d.c. Motor. It's something to do as with the wires in the motor, the electromagnet-outer fields are wound.
What is a Compound Wound Traction Motor?
It is a Direct Current Motor which is wound and creates a magnetic field when energized and does not use a permanent magnet. Jeff S.
What is a magnet motor?
A magnet motor, or permanent magnet motor, is a hypothetical device that, if made to work, would use the attraction and repulsion properties of permanent magnets to rotate a shaft indefinitely, or until the magnetic domains disassociate. The concept of the magnet motor is contrary to several known laws of physics, including the law of conservation of energy. Advocates of such devices insist that magnets have the power to do work, but the reality is that a magnetic field has no power to do work unless energy is stored within the field, which is done by moving the magnet with an outside source, such as the movement of one's hand or an electric current. Once stored, and the motor set in motion, this potential energy is quickly converted to kinetic energy, and then to heat through friction. A magnet motor cannot rotate on its own because it produces no energy of its own, thus the very idea of the magnet motor is fundamentally flawed.
Can you use a dc generator as a dc motor?
Yes you can turn a motor into a generator, if it is a permanent magnet motor.
How do motors that do NOT use magnets work?
Motors that do not have magnets work exactly the same. The permanent magnet is replaced by a electromagnet, which is a coil of wire with a voltage applied to it. This electromagnet is what produces the magnet field necessary for a motor to operate. It is just easier and lighter to use this style of DC motor in larger applications.
Is the refrigerator a magnet?
No, the refrigerator itself is not a magnet. However, the door of the refrigerator may have a magnetic strip to keep it closed.
What is the Use of magnet in electrical fan?
The magnet in an electrical fan is used in the motor to produce a rotating magnetic field. This rotating magnetic field interacts with the coils of wire in the motor, causing them to rotate and drive the fan blades. In essence, the magnet helps convert electrical energy into mechanical energy to power the fan.
What are the two magnets that push and pull in a motor?
The two magnets that push and pull in a motor are the stator magnet and the rotor magnet. The stator magnet is stationary and creates a magnetic field, while the rotor magnet is attached to the spinning rotor and interacts with the stator magnet to generate rotary motion.
How can you get a replacement flywheel magnet for Mercury outboard motor?

What does a field magnet do in a motor?
A field magnet in a motor generates a constant magnetic field that interacts with the magnetic field produced by the armature, causing it to rotate. This rotation creates mechanical energy that drives the motor. The field magnet helps establish the direction of the magnetic field within the motor, ensuring proper operation.
