Are permanent magnets used in doorbells?
no it is not . a temporary magnet is used instead. If you use a permanent magnet, the doorbell will keep on ringing
Why does an electric motor use one electromagnet and one permanent magnet?
An electric motor typically uses one electromagnet and one permanent magnet to create a magnetic field that interacts to produce motion. The electromagnet's field can be easily controlled by varying the electric current, allowing the motor's speed and direction to be changed. The permanent magnet provides a fixed magnetic field that interacts with the variable field of the electromagnet to generate the rotational force needed for the motor to work.
How does generators use magnets to create electricity?
Generators use magnets to create electricity through electromagnetic induction. When the magnet inside the generator spins, it creates a changing magnetic field that induces an electric current in the wire coils of the generator. This electric current is what generates the electricity.
Is an electromagnet stronger than a permanent magnet?
Not necessarily. The key difference between a permanent magnet and an electromagnet is the a permanent magnet does not change whereas an electromagnet's magnetic feild can be altered by varying the current through it. This means that electromagnets are more useful because they can be turned on or off, turned up or down or be put in 'reverse'.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
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.
What would happen if a shunt-excited DC generator was operated at too low a speed?
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
What is a permanent use for a magnet?

Can you magnetize a magnet in order to change it as a permanent magnet by the use of electricity?
No it will only be possible for it to be a temporary one
How does cycle pedal Generator produced electricity?
the pedals drive the wheel, the wheel drive an electrical generator.2 possibilities for the wheel to drive the generator:-the wheel does not have a tire: a belt goes in the rim and drive a puley on the shaft of the generator.-the wheel has a tire: there is a drive roller on the shaft of the generator. the drive roller is pressed on the tire.The generator can be of any kind. They are commonly car alternator or permanent magnet dc motor, but you can also drive an alternative current squirel cage generator. Depending on the chosen generator, you have to use an electric circuit appropriate for the generator.
What is generator brief explain?
A generator is tool that converts kinetic energy into electricity, through the use of magnets which is surrounded by magnetic fields. As a magnet starts turning its magnetic fields collide with a coil that surrounds the magnet. Which induces current, which is electricity.
Can you generate electricity by attaching a battery to a bicycle?
You don't attach a battery to the bicycle but yes you can generate electricity with a bike generator. You use a bike training stand to hold the bike up, mount a DC permanent magnet generator to the wheel, connect the generator through a charge controller to the batteries, and the batteries to an inverter which will then power electronics.

Why won't my split-phase AC motor generate - I've got a Dayton motor I want to use as a generator but no matter how fast I spin the motor it won't generate more than a couple of volts - Help?
You must have a permanent magnet in the field or residual magnetism that produce magnetic flux lines across the rotating conductors. Without an energized coil (electromagnet) or permanent magnet near the conductors, the motor will never be able to create electricity.
What part of the generator is rotated by the drive belt?
A drive belt causes the inside part of the generator rotate. An electric generator can be either a magnet (and magnetic field) rotating and surrounded by wires or a coiled wire rotating in a surrounding magnetic field. EIther way works to generate electricity. The wire is where the electricity is generated. We use more wire to generate more electricity and we coil the wires to keep the size from getting too big. The stronger the magnet, the more electricity is generated. Instead of using a real permanent magnet, we usually make an electromagnet (such as wires wrapped around iron) attached to a battery or powered off the electricity created by the generator. In an automobile it is not called a generator. It is called an alternator because it generates alternating current electricity instead of direct current.
