Explain the following: Several soft iron pins can cling, one below the other, from the pole of a magnet.

Explain the following: When two pins are hung by their heads from the same pole of a magnet, their pointed ends move apart.

Explain the following: Gases can mix up freely with one another.

Which one of the following is not made of soft iron?

Explain the following: The north end of a freely suspended magnetic needle gets attracted towards a piece of soft iron placed a little distance away from the needle.

The time period of viberation of two magnets in sum position (magnets placed with similar poles on one sides one above the other) is 3s. When polarity of weaker magnet is reversed the combination makes 12 oscillations per minutes. What is the ratio of magnetic moments of two magnets?
