Which type of towel is used to clean the magnets?

The correct answer is that a paper towel is used to clean the magnets because paper towels are designed for quick, disposable cleaning tasks. They are typically made from absorbent materials that can effectively trap dirt and grime. When it comes to cleaning particularly sensitive or small areas, such as magnets, using a paper towel helps minimize the risk of leaving behind lint or fibers that could interfere with the magnet's function.

While other types of towels, like cloth towels and dish towels, can be used for general cleaning, they may not give the same level of efficiency in disposable use as paper towels. Cloth towels could retain moisture and dirt, and where sanitization is necessary, using paper towels is preferable since they are single-use and help avoid cross-contamination. Hand towels are often designed for drying hands rather than cleaning surfaces and might not be as effective for this specific cleaning task.
