The shed is not made of iron or steel.
The magnet is not magnetized.
The nail pulled the magnet to the ground.

The reason for this observation is  that the shed is not made of iron or steel.

The special magnetic property of iron is called ferromagnetism. As a result of this special magnetic property, iron can be attracted easily by a magnet. Steel is made from iron so it is also highly magnetic.

In the question, a magnet placed against the wall of a metal shed falls to the ground, where it attracts a nail. The reason for this is that the shed is not made of iron or steel.
