Why is a crane in a steelworks fitted with a large electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.
Where would you expect to find an electromagnet?
two bar magnets
What are two parts of an electromagnet?
An iron core and wire wound around it
What does an electromagnet operator do to release metal attached to the electromagnet?
burat
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What are two advantages of a natural magnet over electromagnet?
A natural magnet is permanent - an electromagnet loses its power when it's switched off.
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.

What are the advantages of using a electromagnet at an rubbish dump?
It helps to separate metals from other rubbish such as paper and plastic.
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
Where would you expect to find an electromagnet?
two bar magnets
Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What is the difference in a common bar magnet and an electromagnet?
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?

What do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
