Another AnswerElectromagnets are necessary for an electric motor to work. Electromagnets are used in ink jet printers to release ink, they activate relays and solenoids. Electromagnets are inside automotive fuel injectors. The old CRT televisions wouldn't work without some high powered electromagnets. Computers would be useless without electromagnets that operate disk drives and relays.Electromagnets are an essential part of all Transformers.
Essentially, modern technology would come to an end without electromagnets.
This requires magnets in general. It need not be an electromagnet; sometimes electromagnets are used, sometimes permanent magnets.
Electromagnets
Electromagnets are useful because some machines need magnets that can stop being magnetic. In junkyards, some machines need to pick up metallic objects, so they need magnets that can turn on and off, which is where a electromagnet becomes useful.
One of the important inventions that use electromagnets include DC shunts. These are common in small toys and many other gadgets that need rotating gears.
Electromagnets do not affect glue.
You can turn electromagnets on and off.
Yes, food processors do have electromagnets.
All electromagnets are magnetic when they are turned on.
You can turn electromagnets on and off.
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
no there is no use of electromagnets in iron box
