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.
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 are electro magnet like bar magnets?
Electromagnets and bar magnets both produce magnetic fields. They can attract or repel other magnetic materials, and the strength of their magnetic field depends on the strength of the current flowing through the electromagnet or the material of the bar magnet. Additionally, both electromagnets and bar magnets can be used in a wide range of applications, from speakers and motors to magnetic levitation systems.
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 was wrapped around an iron bar to create the first electromagnet?
A copper wire was wrapped around an iron bar to create the first electromagnet.
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
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?
Vacuum Repair?

If an electromagnet was free to move how would it move?
Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.
