Magnetic materials are notoriously hard so you will damage an ordinary hacksaw blade if you cit a bar magnet with a hacksaw (but you should eventually succeed if you do not mind dulling a few blades). An angle grinder with a metal cutting disk will work but magnetism is destroyed above the Curie temperature (about 500° C) so you should cool the magnet often as you cut through it (beware of sparks and bits flying off - wear protective clothing, ear and eye protection!).
by the force of attraction in magnet their pieces will re join wd each other. All the broken pieces will become separate individual magnets.
The bar that affects the compass is the magnet, The bar that is attracted to the magnet is iron, and the bar that is not attracted to the magnet is aluminum.
by keeping another magnet or attractive force
Fill the container about half full of water. Float a leaf on the surface of the water, and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll make one, and I thank you for the idea.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center
A bar magnet has two poles, a north and a south. When you break a bar magnet into to pieces, you create two bar magnets, each with a north and a south pole. So the total number of poles will then be four.

sort of. magnetic fields in a bar magnet always run south to north. if you break it in half, that same S-->N direction still applies. in fact if you were to break it up into smaller & small pieces you would still have that relationship. that is to say, you wouldn't have a north only piece and a south only piece.

Each half will become its own magnet with its own north and south poles. The resulting magnets will have a weaker magnetic field compared to the original bar magnet, as some of the magnetic domain alignment will be disrupted during the cutting process.
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.
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.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
Each piece would become a separate magnet with its own two poles, just like the original bar magnet. Cutting a bar magnet does not eliminate its magnetic properties; each piece will still have a north and south pole.
no
Move towards the U magnet so that the poles attach.
No, cutting a candy bar in half will not change its density. Density is a constant property of a substance, and cutting it into smaller pieces does not alter its mass or volume, which are the factors that determine density.
