All electromagnets are magnetic when they are turned on.
AC, its all done with coils- or electromagnets.
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.
pick things upAnother 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.
Electromagnets do not produce energy at all. They require an electric current to make them work so they are consumers of energy.
All electric motors are electromagnets.
Electromagnets do not affect glue.
Unlike normal magnets, electromagnets attract just someof the alloys that contain iron, such as steel and iron, but not all of them. Electromagnets do not attract aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead or pewter.Contrary to some opinions, electromagnets cannot attract cardboard.See also the related question.
Yes, food processors do have electromagnets.
