Initially, no.
At a certain temperature the bar would suddenly lose its magnetism. This temperature is known as the Curie point of the material.
If the magnetism of the bar came from an external source - a solenoid or a permanent magnet - the field would return to its original strength as soon as the bar cooled below the Curie point.
If the bar had been itself a permanent magnet almost all the field would stay gone until the bar was re-magnetised by an external field.

Where is the field around a magnet strongest?
Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
What is the space all around a magnet called?
The space around a magnet where its magnetic influence can be felt is called the magnetic field. It is the region in which magnetic forces are experienced due to the presence of the magnet.
Where there is magnitude of the magnetic field around a permanent magnet greatest?
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most concentrated and where the magnetic force is strongest.
When is a magnetic field is the strongest on a magnet?
the magnet field is the strongest well the summer solstic when the suns gravitational pull is the strongest
What is the invisible force around a magnet called?
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
When does the magnetic domain in a magnet produce a weaker magnet?
When the external magnetic field is removed, the magnetic domain in a magnet can produce a weaker magnet due to randomization of the magnetic moments within the domains, causing them to lose alignment. This results in a decrease in the overall magnetic field strength of the magnet.
Does oil affect the magnetic field of a magnet?
No, oil does not affect the magnetic field of a magnet. Magnets create a magnetic field due to the alignment of their internal magnetic domains, and substances like oil do not interfere with this process or affect the magnetic field strength.
What occurs if the size of the magnet is change?
If the size of a magnet is changed, it can affect the overall strength of the magnetic field it produces. Generally, a larger magnet will have a stronger magnetic field, while a smaller magnet will have a weaker magnetic field. However, other factors such as the magnet's composition and shape can also influence the strength of the magnetic field.
Where is the magnetic field the strongest on a magnet?
The magnetic field is strongest at the poles of a magnet.
What is the definition of a magnet?
A permanent magnet is a magnet that has been manufactured to "permanently" hold its magnetic field. Ferromagnetic material of a desired shape is heated above its Curie point, exposed to a large electromagnetic field, and cooled slowly while being held in that field. This allows the magnetic domains in the material to align themselves with the field of the electromagnet. Further, when the material cools below its Curie point, the magnetic domains will remain in the position they are in when the electromagnet is shut off. The magnet is now a permanent magnet; the magnet "holds" the magnetic field "imprinted" on it.
Why is the deflection in the galvanometer reversed when the magnet is moved in and out in a solenoid?
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.
How is a permanent magnet made?
The material from which the magnet is to be made is heated so that it is above what is called the curie temperature. The material is then allowed to cool in a magnetic field. The magnetic field can be made by coiling wire and passing an electric current through it.

Where is the magnetic field the strongest on a bar magnet?
The magnetic field is strongest at the poles of a bar magnet.
Where is the magnetic force the greatest on a magnet?
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
Is it false that a strong magnet will cause a larger change in motion than a weak magnet?
No, that statement is false. The strength of a magnet affects the magnetic field it generates but not necessarily the change in motion it causes. The change in motion is determined by factors such as mass, distance, and the magnetic field's influence on an object.
