Hint: Every magnet has two poles on its ends where the magnetic field due to it is maximum. These poles are known as the North pole and South pole. The magnetic field originates at the north pole and ends on the south pole. These poles always exist in pairs and cannot exist individually.
Complete step by step answer
A bar magnet is a rectangular shaped magnet. On both ends of a bar magnet, the poles are situated. It is known that the magnetic field lines originate from the North pole and end on the South pole. Thus the ends of the magnet have the maximum magnetic field and when iron filings are brought near a magnet, they stick to the poles or the sides of a bar magnet.
The middle of the magnet does not have as strong magnetic strength as compared to the poles, because no magnetic field lines originate from here and the ones that pass from here are too spread out. Thus very few filings stick to the middle of a bar magnet when it is brought near them.
The following diagram shows the density of magnetic field lines in a bar magnet, the area where these lines are denser, is the area of more magnetic strength.
Therefore, the given statement is false, and option (B) is the correct answer.
Note
It is to be noted that for every magnet, the maximum iron filings stick at the north and south poles because the strength of a magnet is maximum at its poles. The middle of the magnet does not attract many filings because the magnetic field at the middle is not as strong as at the poles.
