The magnet would still have a north and a south pole. No matter how small the magnet is it will always have a north and south pole.
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.
If lightning struck a magnet, the magnet would not be affected much. Magnets are made of materials like iron or neodymium that are not easily damaged by heat. The lightning would likely dissipate through the metal without causing significant changes to the magnet's magnetic properties.
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.
The iron fillings would be attracted to the magnet due to their magnetic properties, separating them from the sulfur powder. This phenomenon is known as magnetic separation and is commonly used to isolate magnetic materials from non-magnetic substances in a mixture.
Yes. For example a lump of iron can be cut in half, yet each half is still a lump of iron. The difference comes when the element is at atomic size; there is no way to break down an atom yet keep the same properties.

Not exactly. All pieces of the magnet retain their ferrous properties, but if they were (for example) dropped, then the shock of the fall could potentially make them lose a bit of magnetism. Extreme temperature changes and high power electric discharges could also decrease the power of the magnet.
As you break a magnet, the remnant (broken piece) shall still remain a magnet with the same properties and poles. However, there is only so far a magnet can be broken. Visualize a magnet. Now imagine to have a knife that would keep cutting the magnet into half. It will reach a point that cutting the 'magnet' further would yield into a particle with no magnetic charge whatsoever. This is called a magnetic domain. Cutting a magnetic domain further would yield into a charge-less particle as it would be obviously incorrect to state that an atom of a magnetized steel bar would still remain a magnet.
No. The aluminum can does not have magnetic properties.
it loses its magnetic properties
Heating a bar magnet above its Curie temperature would disrupt the alignment of its magnetic domains, causing it to lose its magnetization and its magnetic field strength would decrease. As the temperature decreases back below the Curie temperature, the magnet may regain some or all of its original magnetic properties.
Yes. You would take another magnet and run it (with the north end) in the direction of the first magnet that points south. this will change the direction that the magnets north is on.
Pepper is not attracted by a magnet. Pepper is a non-magnetic substance and does not contain any magnetic properties that would cause it to be drawn towards a magnet.
You would use a magnet and the magnet will attract the iron since its magnetic the sand would stay michael Zender
No. Orange juice contains no magnetic material; it would perhaps lower the strength of a field, being a medium with lower permittivity, but not by any significant amount.
When you break a magnet, the regions where the break occurred become the new North and South poles. This is because the magnetic domains within the magnet align themselves in a way that creates these distinct poles at the broken ends.
