Get attracted and stick on together

Yes, a magnet can repel a paperclip if the paperclip is made of a material that is not attracted to the magnet, like aluminum. The magnet's magnetic field will interact with the paperclip's electrons, causing it to repel.
A magnetic field does not interact with a stationary charge.
the magnet gets weaker
When a magnet touches copper, there is no attraction or repulsion between them. This is because copper is not a magnetic material, so it does not interact with the magnetic field produced by the magnet.
it will rest in the north - south direction
Get attracted and stick on together
Iron
The two parts of the magnet will now become two separate magnets, each with a north and a south pole
Cutting a magnet in half will result in two smaller magnets, each with its own north and south poles. This happens because the magnetic properties are not lost when the magnet is cut.
Absolutely nothing since copper is non-magnetic.
If a bar magnet is suspended vertically, it will align itself in the north-south direction due to Earth's magnetic field. The north pole of the magnet will point towards the geographic north and the south pole towards the geographic south.
magnetic field
If you cut off the north pole of a magnet, the remaining part will still have a north and south pole. The cut will create two magnets with their own north and south poles.
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.
