Essential Concept in Moving Charges and Magnetism That You Need To Remember


Moving Charges and Magnetism NCERT solutions are among the essential chapters of 12th Physics that you must prepare thoroughly. This blog will highlight some of the crucial concepts related to this chapter to help with your preparation.

Moving Charge And Magnetic Field

A charge can generate a magnetic field while in motion. Moreover, the magnetic field can interact with a moving charge. Following are the main concepts associated with moving charges and magnetism NCERT solutions:

  • Magnetism: It is the notion of attracting magnetic components such as cobalt-nickel, iron, etc. A body containing the property of magnetism is denoted as a magnet.
  • Artificial Magnets: The permanent artificial magnets are developed of certain metals and alloys such as Alnico, Carbon-steel, Alcomax, Platinum-cobalt, Ticonal, etc. Moreover, these are made of ferromagnetic components that have massive retentivity and coercivity. It can also have any desired shape, such as a U-shaped magnet, bar magnet, magnetic needle, etc.
  • Temporary Artificial Magnet: It is similar to the electromagnet developed by passing a current through a coil wound on the soft iron core. Temporary artificial magnet tends to retain the attracting power for a long time. And they are manufactured of alloy, mumetal, and soft iron.

Properties of Bar Magnet

Following are the properties of bar magnet:

  • Attractive property and poles: A magnet, when immersed into the iron filling, reveals that the attractive potentials of the magnet are at the optimum at the two points that are closer to the ends. These points are poles, whereas the places with minimum attracting power are known as the neutral region.
  • Magnetic Axis and Magnetic Meridian: The line combining the magnet’s two poles is known as the magnetic axis. Additionally, the vertical passing via the axis of the pivoted magnet is reckoned as magnetic meridian.
  • Directive Property and N-S Poles: Its length becomes parallel to the N-S direction when the magnet is adjourned. Moreover, the pole pointing north is the North Pole, whereas the other point is the South Pole.
  • Magnetic Length: The distance between two poles through the magnet’s axis is known as magnetic length. Considering the poles are not at the ends, the magnetic length is lesser than the actual magnet’s length.
  • Consequent-Poles and No-Pole: Magnet monopolies; however, two poles have opposite natures and equal strength.
  • Poles Exist in Paris: When the magnet is divided into several pieces, each piece will become a magnet featuring two opposite and equal poles.
  • Magnetic Induction: Magnet attracts some substance through the concept of magnetic induction by inducing opposite poles in a magnetic material.
  • Magnetic and Non-Magnetic Materials: The components including iron, cobalt, steel, nickel, etc. that are attracted by magnets known as magnetic components such as aluminium, stainless steel, copper, glass, wood, plastic, etc.
  • Demagnetization: A magnet gets demagnetized; it loses its power of attraction if it is hammered or heated.


There you have it; these are some of the core concepts included in moving charges and magnetism NCERT solutions. Of course, you need to ensure that you understand each of these topics correctly to ace your exam.
