Can cotton be used for insulation?
Can cotton be used for insulation? Cotton is non-allergenic and adaptable; it insulates and absorbs more cost effectively than any synthetic or artificial fabric.

Why is there no electrostatic force between two neutral objects?
Why is there no electrostatic force between two neutral objects? The negative/positive charges don’t want to be clumped together in one place if they can help it. But a neutral object does not have a net charge, so it cannot separate the charges in another neutral object. What happens when a positively charged object is […]
What happens when 2 magnets are forced together?
What happens when 2 magnets are forced together? When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. What is the most likely outcome it will become a permanent magnet? A magnetically soft material is placed in a […]
