yes.when you slice a rod magnet it will still be considered as a magnet
No!The smallest particle in which a magnet still has the same magnetic properties is a called a domain. If you split this domain into other remnants, then that particle shall seize to become a magnet and shall just be a piece of matter

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.If you break the magnet, it is still a useful magnet.
If a bar magnet is broken in half, each piece will become its own smaller magnet with its own north and south poles. The strength of each magnet will be weaker compared to the original bar magnet. The overall magnetic field will be distributed between the two smaller magnets.
No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
Yes, a magnet can be submerged in oil and still attract iron. The presence of oil does not interfere with the magnetic field generated by the magnet, as oil is not a magnetic material. Therefore, the magnet will still be able to attract ferromagnetic materials like iron, regardless of being in oil.
It is so far experimentally impossible to separate the North Pole from the South Pole. Even if you cut the magnet into little pieces, it'll still remain a magnet because there will still be a North pole and a South Pole
Yes
Yes, each half still has magnetic properties.
If it is a magnet, then it can still attract to a refrigerator. If it is a lump of hot metal or hot ceramic, then only gravity will provide attraction. The curie temperature describes when it goes from being a magnet to being a lump.
When a bar magnet is cut in half, each half will become a new magnet with its own north and south poles. The magnetic field strength of each half will be approximately half that of the original magnet, but both halves will still exhibit a magnetic field. The overall field strength in the vicinity may remain similar, but the individual magnetic dipoles created will have reduced strength compared to the original magnet.
