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.
How are temporary and permanent magnets alike?
Both temporary and permanent magnets generate a magnetic field, attracting objects made of magnetic materials. They both have a north and south pole and can be used in a variety of applications such as motors, generators, and sensors.
Do doorbells have electro magnets in them?
Yes, most doorbells have an electromagnet inside them. When the doorbell button is pressed, the circuit is completed, activating the electromagnet which causes a hammer to strike the bell or chime, producing the ringing sound.
What does a magnet do in a microwave?
A magnet in a microwave can potentially cause sparks, arcing, or damage to the microwave itself. This is because the microwaves emitted by the oven can cause the magnet to become hot and possibly catch fire. It is not recommended to put magnets inside a microwave.
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.
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)
What uses an electromagnet?
A loud speaker can use electro magnets and i hope this helps =)
What are electro magnets used in?
car wreck (scrapyards) metel dedectors at airports
What controls both the levitation of the cars and the trains speed?
(electro) Magnets in the "track".
What are electro magnets used for?
They can be used in Junk yards to pick up junk. They can be used in a Dentist.
