What else can I help you with?
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.
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.
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!
The magnetic field of an electromagnet is similar to that of a magnet?
bar
What is the different's between a electromagnet and a bar magnet?
electromagnets carry more energy and are mainly found in motors................
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?
Is the magnetic field of an electromagnet different to a bar magnet?
The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
What advantage does a electromagnet have over a bar magnet?
The electromagnet can be turned on and off depending on whether it's needed or not.
What is different about an electromagnet compared to a regular magnet?
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
Using the north pole of a bar magnet how can you prove that a nail has become an electromagnet?
Put the South pole of the nail against the bar magnet to see if it attracts or repels.
