If a bar magnet's neutral region is broken into tow, what will mist likely occur

a. one segment will have only a north pole, the other segment will have only a south pole
b. each of the tow segments of the original bar magnet will have a north and south pole
c. the segment that's longer will have a north and south pole
d. neither segment will have a north or south pole

The answer is C. The north post of one magnet pulls in the south shaft of a moment magnet, while the north shaft of one magnet repulses the other magnet's north shaft. So we have the normal saying: like shafts repulse, dissimilar to posts draw in. A magnet makes an undetectable region of attraction surrounding it called an attractive field.

Assuming that the division of the magnet was gentle in nature, so as to not disturb the alignment of the domains, the answer is B. each of the two segments of the original bar magnet will have a north and a south pole. This is due to the fact that a magnet is essentially filled with bundles of magnetic domains, each having its north pole facing towards the magnet's north pole and its south pole facing the magnet's south pole. Therefore, cutting gently will only expose the poles from the middle of the magnet.

Particle exchange energy though elastic collision , hope this .
