What is Bar Magnet?

A bar magnet is a rectangular piece typically made from iron, steel, or a ferromagnetic substance, having distinct north and south poles. Even if it’s broken, each fragment will maintain its unique identity with retained poles.

Poles of Bar Magnet

A bar magnet has two poles:

  • North Pole
  • South Pole

These poles play an important role in magnet’s behavior and interactions.

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.

Bar Magnet as Equivalent Solenoid

A bar magnet can be modeled as an equivalent solenoid. The magnetic moment of a bar magnet as an equivalent solenoid can be derived by calculating the axial field of a finite solenoid carrying current. The similarity between magnetic field lines of a bar magnet and solenoid is that a bar magnet can be thought of as a large number of circulating currents in analogy with a solenoid. The image of magnetic field of a Solenoid is added below,...
