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.

Are electromagnets used in generatorsto transform mechanical energy into electrical energy?
This requires magnets in general. It need not be an electromagnet; sometimes electromagnets are used, sometimes permanent magnets.
What is the flow of electromagnets called?
Electromagnets
What are four types of electromagnets?
The four types of electromagnets include solenoid electromagnets, flat-faced electromagnets, cylindrical electromagnets, and horseshoe electromagnets. Each type has unique features and applications depending on their design and magnetic field strength.
What makes electromagnets useful?
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.
Do electromagnets affect glue?
Electromagnets do not affect glue.
Do food processors have electromagnets?
Yes, food processors do have electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
How are electromagnets different from permanent magnet?
Electromagnets are temporary magnets that require an electric current to generate a magnetic field, which can be turned on and off by controlling the current flow. Permanent magnets, on the other hand, retain their magnetism without the need for an external power source. Electromagnets are versatile and can have variable strength, while permanent magnets have a fixed magnetic strength.
How are electromagnets and permanent magnets alike and different?
Electromagnets and permanent magnets are both capable of producing a magnetic field. The main difference is that electromagnets require an electric current to generate a magnetic field, while permanent magnets retain their magnetic properties without the need for an external electrical source.
What are the electromagnets called that are used at junkyards?
The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
In what ways do electromagnets differ from other types of magnets?
Electromagnets differ from other types of magnets because they require an electric current to generate a magnetic field, whereas permanent magnets do not need electricity. Additionally, electromagnets can be turned on and off by controlling the flow of electricity, allowing for greater flexibility in their use.
How do trains levitate?
Electromagnets on the track repel electromagnets on the bottom of the train.
