magnets
A magnet has two poles, called North and South. Take two magnets and stick the ends together. You'll find N-S and S-N stick together (attract). N-N and S-S push apart (repel).

The attraction or repulsion of magnets depends on their magnetic polarity. Like poles (north-north or south-south) repel each other, while opposite poles (north-south) attract. This behavior is due to the interaction of magnetic fields.
it repels the magnets away from each other the same would happen if you put an N and N together
The magnet is placed over a super conducting material. Because super conductors conduct electricity with zero resistance, it repels the magnet making it float. The super conductor is usually a piece of YBa2Cu3O7 cooled to below 92 degrees kelvin. At this temperature, the substance changes state from a solid to a bose-einstein condensate and is a super conductor.
Magnets always align in N-S direction because the earth itself behaves lika a huge bar magnet. The north pole of the bar magnet attracts the geographical south pole and the south pole attracts the geographical north pole. That is why magnets always align in N-S direction.
The field lines have no start or stop. They form closed loops and can never cross. The field lines are found inside and outside the magnet. From the point of view looking from inside the magnet the field lines appear to be (say) S to N, while outside the lines appear to be N to S. ( you could choose the opposite convention) +-->---| S inside -->--------- N | --- outside-->-+ +-----------<-----------<-----------<---------------<-+
If one magnet's North Pole faced another magnet's North Pole, the magnets would repel eachother, meaning they would push away from eachother. If you put a North and a South pole together, however, they would attract, or come together. N+N= Repel S+S= Repel N+S= Attract S+N= Attract Well. I guess opposites really DO attract...
Most fridge doors are made of steel which is magnetic. When you bring N/S pole of Magnet near the door it creates oppposite ple S/N on the door and due to attractive force the manet sticks to the fridge.
Breaking a magnet into smaller pieces weakens its overall magnetic field, as each piece becomes a separate magnet with its own north and south poles. The smaller magnets may have different magnetic strengths and orientations compared to the original magnet.
This is a somewhat tricky question to answer. But you can basically imagine a magnet to be made up of a large amount of "elementary magnets", all of which have a north and a south pole, like this:(N---S) (N---S) (N---S) (N---S) The combined magnetic field is the combination of each of the individual magnetic field; and since each of those point in the same direction, in this case north to the left, the combined magnetic field will also have north to the left. If you break the magnet up, you will get smaller pieces, but the "elementary magnets" will still point in the same direction.
