Heating a bar magnet with solenoid demagnatise it.
The magnetic field outside a solenoid behaves similarly to that of a bar magnet because both have field lines that form a pattern resembling that of a bar magnet, with the field lines curving around from one end to the other.
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.
The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.
A solenoid magnet, which is a long coil of wire wrapped around a ferromagnetic core, has a similar magnetic field to that of a bar magnet. This is because the magnetic field created by the current flowing through the wire generates a magnetic field similar to that of a bar magnet.
A solenoid, which is a long coil of wire, produces a magnetic field similar to that of a bar magnet when a current passes through it. The magnetic field produced by a solenoid is confined within the coil and has north and south poles along its axis.
a bar magnet
A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.
The magnetic field in a solenoid resembles the field of a bar magnet, with field lines running parallel to the axis inside the solenoid and forming loops around the outside.
The magnetic field outside a solenoid behaves similarly to that of a bar magnet because both have field lines that form a pattern resembling that of a bar magnet, with the field lines curving around from one end to the other.

The magnet bar is used for stirring solutions.

When current is passed through a solenoid coil, magnetic field produced due to each turn of solenoid coil is in the same direction. As a result the resultant magnetic field is very strong and uniform. The field lines inside the solenoid are in the form of parallel straight lines along the axis of solenoid. Thus, the solenoid behaves like a bar magnet.
Yes. DC can pass through. As it passes through then solenoid would act as if a bar magnet.
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
