Solution

Bar magnet

  1. A magnet consisting of ferromagnetic materials is known as a bar magnet.
  2. The Magnet's magnetism is due to the ferromagnetic material.
  3. A bar magnet is a rectangular piece of magnet that, like other magnets, aligns itself along the earth's magnetic field when suspended freely.
  4. In the same way that opposite poles of a magnet attract and like poles repel each other, a Bar Magnet follows the same rule while aligning itself to the earth's Magnetic field.

Magnetic meridian

  1. The magnetic meridian is a line that connects the magnetic north and south poles and goes through the world.
  2. This is the horizontal component of the magnetic force lines that run down the surface of the earth.
  3. Magnetic lines of force on the earth are parallel to the magnetic meridian.
  4. The earth's magnetic north pole is located south of the globe's geographic north pole, which is defined by the rotational axis.

Placing a bar magnet in the magnetic meridian

  1. The neutral point of a bar magnet placed on the magnetic meridian with its north pole facing geographic north will be on the equatorial line of the magnet.
  2. If the magnet's north pole points to geographical north, the magnet's and earth's fields will point in opposing directions along the equatorial line of the magnet, yielding two neutral spots on the equatorial line that are equidistant from the magnet's axis.
