What is an electromaget?
An electromagnet is made by wrapping many coils of copper wire round an iron bar. When electricity is send along the coiled wires, the iron bar becomes magnetised until the electricity is switched off.
What is the difference between a strongly magnetized nail and a weakly magnetized nail?
In an un-magnetised nail there are tiny domains, each in themselves would be a little magnet, however, in a magnetized steel nail the magnetic "domains" tend to be lined up in the same direction. A domain is a tiny magnet because electrons are spinning with the same orientation. Refer to the related link in the Related Links section below for more details.
What can be made from iron?
Iron is a element so various things can be made out of iron.
Is magnet use in iron?
Magnets is made of iron. Magnets are attracted to anything made out of iron.
Can a magnet attract lightning?
If the magnet is made of metal then it can act as a good conductor to the Earth like any other metal. The fact that it is magnetised does not attract the lightning.

How do magnets behave?
Magnets are made from magnetic materials. These are metals that can be magnetised or will be attracted to a magnet. Most materials are not magnetic, but iron, cobalt and nickelare magnetic. Steel is mostly iron, so steel is magnetic too.
When a current-carrying wire is made to form a coil around a piece of iron the device is called?
A solenoid with iron core also known as electromagnet
What is haemozoin?
It is a pigment that contains iron. When it accumulates it becomes granules in malaria parasites. This pigment is the bad result made by hemoglobin.
How is the chemical energy in fossil fuels changed to electricity energy?
The fossil fuel is combusted in a boiler. In doing so the boiler is filled with water; it boils ; and forms steam under pressure. This pressurised steam is passed from the boiler to a turbine , which the steam makes the turbine rotate. This turbine rotation is connected to a long shaft made of magnetised iron , which . This magnetised iron is rotated inside a coil of wire.. Remember when rotating a magnet inside a wire coil makes the electrons in the wire coil move, hence electricity.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
spread out from one pole and curve around to the other
What happens to the cast iron rod when manganese is added to it?
It becomes harder and tougher. Manganese steel is what soldiers helmets were made out of in WW II.
What is iron pipes made of?
Iron pipes are made of iron.
What are iron pipes made of?
Iron pipes are made of iron.
Is pen knife magnetic?
Usually it is not magnetic, but, being made from quality steel it can easily be magnetised bu rubbing it against a magnet.
