Pole Strength of Bar Magnet
The pole strength of a bar magnet is the strength of a magnetic pole to attract magnetic materials towards itself. The magnetic force of a bar magnet is strongest at the poles. The pole strength is related to the magnetic moment of the magnet, and it is the product of the pole strength and the length of the magnet.
Formula of Pole Strength
Formula to find pole strength of a bar magnet is given by:
P = W/T
Where,
- P is the Strength of Magnetic Pole
- W is the Work Done in Moving Magnet around the Wire
- I is Electric Current in Wire
SI Unit of Pole Strength
- SI Unit of pole strength of a bar magnet Ampere-meter (A.m).
- Dimension of Pole strength is, [LA]
Bar Magnet
Bar Magnet is a magnet that is rectangular in shape and has two poles, the North Pole and South Pole. The magnetic field of a bar magnet is maximum at its pole and minimum at its center. Bar Magnets are made up of Iron, cobalt, or any other Ferromagnetic materials that show magnetic properties. Bar magnets can be of various types including Cylindrical Bar magnets and Rectangular Bar magnets.
Bar magnets have fascinated us for centuries due to their practical applications in everyday tools and advanced technologies. In this article, we will dig deep into What a is Bar Magnet, the Properties of the Bar Magnet, the Application of Bar Magnet, and others in detail.
