A coated copper wire, something round and metal that can magnetize, and a source of Direct Current (DC)
First; wrap a thin, coated wire around a round metal object, such as a bolt or nail. Make sure said metal will stick to a magnet in the first place. Generally iron must be present in the metal for it magnetize, but other metals also work. Just stick with something that can rust though. So Once you have the wire wrapped around the bolt, find yourself a battery or some other source of Direct Current (Alternating Current has a totally different effect)
Attach one end of the wire to the positive lead and the other to the negative lead on your source, and a small magnetic field will be generated.
Electrons moving in a circular motion of almost any kind will generate some type of magnetic field. Increasing the Amperage or Voltage will increase the Size and Power of the Magnetic Field

∙ 12y agoMost loudspeakers use an electromagnet to vibrate the cone of the speaker. Many devices use a solenoid, which is an electromagnet pushing a rod, as the operator. All electric motors use electromagnets to produce the motion.

Where can a electromagnet be found?
In almost all rotary electrical equipment, and associated with much equipment that is not itself electric - in things such as alternators/dynamos.
What equipment do you need to separate mixtures?
Many equipments: separation funnel, a distillation apparatus, centrifuge, electromagnet, sieve, etc.
Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.

How can an electromagnet attract plastic?
A pure hydrocarbon/fluorocarbon plastic contains no ferromagnetic material, so it will not be influenced by a magnet. If a plastic is loaded with ferromagnetic material (such as iron particles), then it will be influenced by an electromagnet. Ceramic materials loaded with ferromagentic materials, known as ferrites, are widely used in electrical and electronic equipment.

Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
