Question

The metal sphere in FIGURE Q$29.2$ hangs by a thread. When the north pole of a magnet is brought near, the sphere is strongly attracted to the magnet. Then the magnet is reversed and its south pole is brought near the sphere. How does the sphere respond? Explain.

Short answer

The statement is proved below.

Step-by-step solution

Given Information 

We need to find the sphere respond.

Simplify

Magnetic materials are the material that responds to the magnetic field of a bar magnet. The charges on the magnetic materials accumulate on both sides, where one side accumulates the positive charges and the other side accumulates the negative charges. This accumulation converts the magnetic in that repels or attracts the bar magnet. Therefore, the alignment of the positive and the negative charges depends on which pole of the magnet faces the sphere, so in both cases, the sphere is attracted to the magnet.
