A bar magnet is a permanent magnet that produces a magnetic field without the need for an external power source. An electromagnet is a temporary magnet that produces a magnetic field when an electric current flows through a coil of wire. The strength of an electromagnet can be controlled by adjusting the amount of current flowing through the coil.

Is the magnetic field of an electromagnet different to a bar magnet?
Yes, the magnetic field of an electromagnet is different from that of a bar magnet. An electromagnet's magnetic field can be turned on and off by controlling the electric current, whereas a bar magnet has a fixed magnetic field. Additionally, electromagnets can have stronger magnetic fields than bar magnets, depending on the current passing through the coil.
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?
Both solenoids and bar magnets produce a magnetic field. Both have north and south poles. However, solenoids are typically more efficient at producing a magnetic field when a current flows through them, whereas bar magnets retain their magnetism without needing a current.
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?
Both an electromagnet and a permanent magnet produce magnetic fields. However, an electromagnet is made by passing an electric current through a coil of wire, while a permanent magnet retains its magnetism without the need for an external electric current.
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?
An electromagnet can be turned on and off by controlling the flow of electric current, while a bar magnet has a fixed magnetic field. Additionally, the strength of an electromagnet can be adjusted by changing the amount of current flowing through it, which is not possible with a bar magnet.
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?
Yes, the magnetic field of an electromagnet is different from that of a bar magnet. An electromagnet's magnetic field can be turned on and off by controlling the electric current, whereas a bar magnet has a fixed magnetic field. Additionally, electromagnets can have stronger magnetic fields than bar magnets, depending on the current passing through the coil.
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.
