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.
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.
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
It requires a current through a coil of wires.
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
the world is
a electromagnet is bigger than a bar magnet
An electromagnet can be turned on and off.
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
It will pick up the nails the same way a bar magnet would do!
An electromagnet is temporary because the field disappears when the current is switched off.
Both are magnetic.
bar
a bar magnet...
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?
The electromagnet can be turned on and off depending on whether it's needed or not.
With an electromagnet, the magnetism can be turned on and off according to the whim or need of the operator.
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.
