Are permanent magnets are 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
What is the use of a magnet in a motor?
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.
Is iron oxide used in magnets?
Yes, we can see the use of iron oxide (the Fe2O3 kind, which is iron (III) oxide) used in magnets. There are a number of different things that could be used in a magnet, but simply using this material, often referred to as ferrite, and a little bit of some other materials to make up the ferrite, will allow for the construction of a magnet.
Does a magnet attrack to copper?
No, they won't. Copper, while it is a good conductor of electricity, is not a ferromagnetic material, and a magnet won't be magnetically attracted to it. (They will stick to anything if you use enough glue!)
Do water heaters use magnets?
Some of the water heaters uses magnets. Magnets softens the water.
How does the use of keepers help eliminate self-demagnetization in the storage of magnets?
Magnetic keepers can be thought of as materials that complete the magnetic circuit of the magnet. They do this by providing a paramagnetic link from one pole of the magnet to the other. That way the magnet can resist the effects of other magnetic fields that might tend to depolarize or demagnetize it.
What are the different types of magnet?
bar magnet, horse shoe magnet,ball ended magnet and cylindrical magnet.I recomend doing the iron shavings and bar magnet experiment.x.x TRY IT .There are 3 types o magnets parmanent, temporary, and electromagnets.you can also use water andblue food colloring to create a magnetic field.Bar Magnet, horseshoe magnet etc
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.
What is an fact about a magnet?
Magnets attract all ferus metals. They use magnets to treat cancer.
Is magnet use in iron?
Magnets is made of iron. Magnets are attracted to anything made out of iron.
What are some use of magnets?
what is the magnet ? magnet is the solid substance that attracts the iron.
How could you use a magnet to find out where North is?
magnets attract
How can YOU use magnets?
You could use magnets to push things like another magnet or you could pull metal things to it.
What country invented the magnet?

What is a everyday use for a magnet?
There are refrigerator magnets; you can put a school picture onto a thin magnet and put it on a refrigerator (as long as it has a metal door)There are car magnets; such as a sports team symbol with a magnet on the back. You just put them on the back of your car.
