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.
Is a horseshoe electromagnet bar magnet or a magnet pole a example of a temporary magnet?
A horseshoe electromagnet is an example of a temporary magnet because it only exhibits magnetic properties when an electric current is passed through it. When the current is turned off, the magnetism disappears.
What are the similarities and differences between a solenoid and a bar magnet?
DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.
How is an electromgnet and a bar magnet different?
The bar magnet is what is termed a permanent magnet . This means that it is "always on" and can be used to do things like pick up paper clips. The electromagnet is created by winding a coil of wire about a ferromagnetic core and running a direct current through that coil. Only when the current is flowing will the electromagnet be operating. With the current switched off, the magnetic field around the coil of wire disappears, and the power of the electromagnetic disappears as well.There are some "fine points" associated with a further extension of this post, but the basic answer to the question is as written.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 is an electromagnet similar to a magnet?
The reason is because an electromagnet is hooked up to an artificial energy force, while a magnet is a charged piece of metal example: a battery hooked up to a piece of iron attracts paperclips but a magnet can be made by stroking a paperclip against a bar magnet to create a temporary magnet somewhat how a compass works
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?
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
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.
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!
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 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 Difference of bar and horceshoe magnet?
One key difference between a bar magnet and a horseshoe magnet is their shape. Bar magnets are long and rectangular, while horseshoe magnets are U-shaped. Another difference is their magnetic field strength, with horseshoe magnets typically having a stronger magnetic field at the poles compared to bar magnets.
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.

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.
