An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

How is electromagnet different from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
How are the uses of an electromagnet different from those of a permanent bar magnet?
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
How are electro magnet like bar magnets?
a bar magnet and a electromagnet are alike in many ways. the are alike because both of them are magnets. but there are plenty other ways they are alike

How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet

An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
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.

If an electromagnet were used instead of a bar magnet to pick up nails the electromagnet would do what?
It will pick up the nails the same way a bar magnet would do!

A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
Is a horseshoe electromagnet bar magnet or a magnet pole a example of a temporary magnet?
An electromagnet is temporary because the field disappears when the current is switched off.
The magnetic field of an electromagnet is similar to that of a magnet?
bar
How are electromagnet and a bar magnet alike?
Both are magnetic.
What is the magnetic field of an electromagnet similar to?
a bar magnet...
