Question

The strength of a bar magnet is maximum at its center. (T/F)

Hint:

The magnetic field strength in a bar magnet is strongest at the poles, where the magnetic field lines are concentrated.

Answer 1

Step 1: Magnetic field strength in a bar magnet.
The strength of the magnetic field in a bar magnet is not uniform across its length. The magnetic field strength is strongest at the poles of the magnet, where the magnetic lines of force are most concentrated. At the center of the magnet, the field strength is weaker because the lines of force are more spread out.
Step 2: Understanding the magnetic field distribution.
In a bar magnet, the magnetic field is created by the alignment of magnetic domains. The field lines exit from the north pole and enter the south pole. The magnetic field is strongest near the poles and weakest at the center, where the field lines are more evenly distributed.
Step 3: Conclusion.
Thus, the strength of a bar magnet is maximum at its poles, not at its center, making the statement false.
