Question

Maximum iron filings stick in the middle of a bar magnet when it is brought near them. (True or False)

• A. True
• B. False

Answer 1

The correct option is B False

Magnetic Field Lines

1. Magnetic field lines are imaginary lines that give us the strength and direction of the magnetic field at that point.
2. These lines originate from the north pole of a magnet and go to the south pole.
3. The lines travel from the north pole to the south pole outside the magnet and from the south pole to the north pole inside the magnet.
4. The density of lines present in a given area gives us the magnetic field strength at that point.

Density of Iron Fillings

1. Magnetic field lines are generally denser near the poles than in the middle of a magnet.
2. Therefore, the magnetic strength on the poles is more.
3. Since iron filings are attracted by a strong magnetic field, they will stick more to the poles of a magnet than in the middle.

Hence, the given statement is false.
