A long magnet is broken into 10 piece?How many north pole will form
To determine the number of north poles that will form when a long magnet is broken into 10 pieces, we need to understand the magnetic property of magnets.
When a magnet is broken, each piece retains its magnetic properties. This means that if the original magnet had a north pole at one end and a south pole at the other end, each piece will also have a north and a south pole.
In this case, since the original magnet had only one north pole and one south pole, breaking it into 10 pieces will result in 10 separate magnets, each with one north pole and one south pole.
Therefore, when a long magnet is broken into 10 pieces, there will be 10 north poles formed.
