Bar magnets and how are they used
A magnet's power is focused at the poles and lessens at the sides. Bar magnets are generally the weakest shape, because the poles have the smallest area. They are, however, the most common shape used in everyday life such as refrigerator magnets and compasses.
Bar magnets are also commonly used for demonstrations in the classroom. For example, you can use the bar magnet to reveal a magnetic field by spreading metal shavings on a piece of paper concealing a magnet.
