Magnetism

Things to remember

• Magnets are generally of two types: natural magnets and artificial magnets.
• Molecular theory of magnetism states, “If molecular magnets align in a row, then the substance exhibits magnetic property. If they are kept haphazardly, they do not exhibit magnetic property."
• If molecular magnets align in a row, then the substance exhibits magnetic property.
• A magnet gets demagnetized by Dropping regularly from a certain height, Hammering , Rubbing the same pole, etc
