Answer:

The purpose of step 1 is to induce magnetism into the needle, so that it retains magnetism and behaves as a magnet after the process.

Explanation:

The method of production the needle magnet in the procedure is the single stroke. This process involves a continuous stroking of a magnetic object (e.g needle) repeatedly for a period or number of times with a permanent magnet. Thus, when the permanent magnet is removed, the object retains magnetism, and behaves like a magnet.

The importance of the stroking process is the turn a magnetic object to a magnet by inducing magnetism into it.
