Joe follows the procedure below to make a compass.1. Move a magnet from the top of a needle to its point fifty times.2. Lay the needle on a cork that is floating in a bowl of water.3. Observe the direction that the needle points. What is the purpose of step 1

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.
