Why does a broken magnet shows repulsion when wetry to bring it back to position?
The two broken pieces will repel as the near poles on them are of the same polarity after breaking. There is no pole reversal that has taken place.
Question 16
Fig. shows a magnetic compass. What will happen to the position of its needle if you bring a bar magnet near it? Draw a diagram to show the effect of the needle on bringing the bar magnet near it. Also, draw the diagram to show the effect when the other end of the bar magnet is brought near it.
Give reasons.
(a) A magnetic needle comes to rest in the north-south position.
(b) A magnetic needle is used in a mariner’s compass.
(c) If a bar magnet is suspended vertically it does not hang in the north-south direction.
(d) Repulsion rather than attraction is the test for identifying a magnet.
