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 is electromagnet different from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
What supplies would you need to make an electromagnet?
You need an iron bar, some copper wire and a battery.
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
What is it called when you wrap a wire around an iron bar and connect it to a battery?
It is called an Electromagnet, when disconnected, it loses it's magnetism.
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.
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.
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!
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 are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
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...
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 advantage does an electromagnet have against a bar magnet?
With an electromagnet, the magnetism can be turned on and off according to the whim or need of the operator.
