Ah, magnets are a vital piece of physics used from the humble fridge magnet, to large computers, these forces are, well, a force.
Magnetic forces are a force that pulls similar to the gravitational force of the earth, magnetic forces pull on each other to pull objects closer.
The orientation of a magnet is important as the different poles cause the magnet to do different things. Now you are probably wondering, "Poles what is that?", there are two poles on a magnet, and each pole is different as one pole is positive and the other is negative, now if you were to put two magnets one facing the positive side and the other on the negative side, they will attract and pull each other closer.
Now if you were to do that with say, two negatives or two positives, they will repel as they are pushing away from each other.
The strength of the magnetic force decreases with range. Further the magnets are from each other, the weaker the magnetic force.
If two magnets have a strong force at 5 centimetres, increasing that distance to 10cm makes the forces weaker.
For example, MagLev trains use super strong magnets to push the train above the tracks to make the train have no friction due to wheel spin, and due to friction can travel at speeds of 500km or 310 miles per hour.
