Because they are always positive or negative, and they are equal and opposite.
In fact there is no such thing as magnetic poles, theoretically they don't exist but the idea of magnetic poles is introduced as a way of explaining magnetism to children.
Another Answer
The terms, 'positive' and 'negative' are applied to electric charges, NOT magnetic poles. It is also quite incorrect to say that magnetic poles 'do not exist', as they most-certainly do. They can be identified by bringing a compass needle (itself, a small magnet) near to the end of a permanent magnet; the north pole of the compass needle will then indicate the south pole of the magnet.
We know that like magnetic poles repel and opposite magnetic poles attract. North will repel north and south will repel south. On the other hand, north and south attract each other.
No, there are two magnetic poles denoted by North (N) and South (S). N does not attract N, S does not attract S. N & S attract each other. Like pole repel.
Magnetic poles act like charges, they attract(opposites) and repel (same).
the north and south poles....
no
Like poles repel each other, while opposite poles attract each other.
In magnetism, opposite poles will always attract each other.
Yes, Because they repel each other.
Magnets have a south pole and a north pole. Like poles of two magnets repel and opposite poles attract each other.
They have the strongest magnetic forces :) precious
they move away from each other!
Same poles attract where as opposite poles repel. N-N= repel N-S=attract S-N=attract S-S=repel
We know that like magnetic poles repel and opposite magnetic poles attract. North will repel north and south will repel south. On the other hand, north and south attract each other.
A magnetic field is created when the atoms of a magnet line to the north or south pole of the magnet. When two opposite poles face each other, the fields, and the atoms inside the magnet, line up, and this causes the attraction between the poles.
No, there are two magnetic poles denoted by North (N) and South (S). N does not attract N, S does not attract S. N & S attract each other. Like pole repel.
opposite poles-attracts each other and like poles- repel each other
Magnetic poles act like charges, they attract(opposites) and repel (same).
