If a wire is wrapped around a ferromagnetic material (those which are attracted by a magnet) and a current is flown through the wire, the material behaves like a magnet. This phenomenon is known as electromagnetism. The electromagnet can attract other ferromagnetic material just like any magnet. Usually a soft iron-core is used for good results. By such a phenomenon you get a temporary magnet whose magnetic property can be switched on or of by a switch! You can try this at home by wrapping a wire around an iron-nail and using a battery for current.
Hope this helps:)

When you cause a current flow through a wire, the flow of electrons will induce a magnetic field. Adding an iron core within the coil, will make the magnetic field stronger. This is then an electromagnet.

What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
Is a circuit breaker an electromagnet?
No.
How fast does an electromagnet have to spin to produce 1megawatt?
A spinning electromagnet does not produce power without other components that you need to specify.
Does electromagnet work only on DC?
They normaly are. AC ones tend to buzz. The core has to be of soft iron or laminate, so that the field collapses properly when the current is switched off.
A safety device that uses an electromagnet to shut off the circuit is called a?
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
How do electromagnet fire alarms work?
the electromagnet makes the door close when a fire alarm goes off
Do you have to connect a cell to work an electromagnet?
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
What does a battery contribute to an electromagnet to help it work?
A core
What in an electromagnet the what turns the drive shaft which does the work?
the armature
How does an electromagnet work in blender?
it connets to the bottom of the machine
How does lectromagnet work in loud speakers?
The electromagnet is a very important part of loud speakers. The electromagnet is always placed in the front of the magnet. When the electricity goes through the electromagnet the field is changed and this produces the vibrations in speakers.
In an electromagnet that turns the drive shaft which does the work?
The driveshaft carries the power but the whole unit does the work.
In an electromagnet which turns the drive shaft that does the work?
The driveshaft carries the power but the whole unit does the work.
What makes the electromagnet work?
maybe electrical energy i don't know
How do make an electromagnet stop working?
An electromagnet is powered by electrical current and that current can be adjusted to different levels of magnetism,Êso if you disable its electrical connection it will not work.
Can an electromagnet work underwater?
Yes it can because water will not interfere with the magnet as it is working
How does electromagnet work in separation?
How does electromagnet work in separation? It is when calcinations is moved into a moving belt and passes under two pairs of electromagnets. The first pair of eleronmagnets is to draw off any iron ore the second pair attracts the wolframite.
