What else can I help you with?
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
What do electro magnets do?
Electro magnets are magnets created by wrapping a conductive wire around a core and passing an electric current through the wire. They produce a magnetic field when the electric current flows through them, which can attract or repel nearby magnetic materials. Electro magnets are used in a variety of applications such as electric motors, speakers, and magnetic resonance imaging (MRI) machines.
Whyb are natural magnets noy used in cranes to lift heavy loads?
Natural magnets are not strong enough to lift heavy loads typically encountered in crane operations. Man-made magnets, such as electromagnets, can be controlled and adjusted to generate the necessary magnetic force to lift heavy objects more efficiently. Additionally, natural magnets can lose their magnetism over time, making them unreliable for industrial applications.
Is there a difference between magnets and electromagnets?
"electro magnets" are magnetic ONLY when electricity travels through a coil of wire surrounding them. "Magnets", as you state it, are permanent magnets and remain so independent of and not dependent upon any additional electrical charge.
Where would you expect to find an electromagnet?
Electromagnets are commonly found in various applications such as electric motors, MRI machines, speakers, and doorbells. They are also used in industrial settings for lifting and moving objects using magnetic force.
What things use electo magnets?
tv,washing machines,hoovers,phones,doorbells and tape recorders all use an electro magnet.
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.
How are solendoids related to electro magnets?

Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial magnet.
Are permanent magnets are used in doorbells?
Yes, permanent magnets are commonly used in doorbells to create the magnetic field needed for the electromechanical mechanism to operate. The magnets help in generating sound by attracting and repelling the internal components of the doorbell to produce the ringing noise.
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
What has electro magnets in them?
Lots of things do. For example, relays. (The electronical component)
Are permanent magnets used in doorbells?

What uses an electromagnet?
A loud speaker can use electro magnets and i hope this helps =)
