Magnetic Effects of Current

Introduction The Earth’s magnetic field and magnetic elements are free-floating magnetic needles that come to rest roughly along the geographical north-south axis of the Earth. This demonstrates that the Earth works as a massive magnetic dipole, with magnetic poles located at its poles. Because the magnetic needle’s north pole will come to rest pointing at […]

Magnetic permeability is a constant that defines the magnetic property of that material. Like mass, it is also one of the most fundamental properties. The value of magnetic property tells how much magnetic intensity is required to magnetise that object. In simpler words, we can say that it is the measurement of the number of

A dimensional formula is a mathematical formula that represents a physical quantity in terms of fundamental quantities, such as mass, length, and time. By using dimensional formulae, we can see how fundamental quantities are raised to different powers to build a new physical quantity. The powers of fundamental physical quantities are referred to as dimensions.

When considering the circular motion of electrons, the genesis of magnetism can be explained. Inside the atoms, electrons move in circular orbits around the nucleus, analogous to a circular coil conveying current. The orbital magnetic moment is created by the electron’s orbital motion. A spin magnetic moment is created when electrons spin about in their

Introduction You think water, woods, organic compounds, petroleum, plastics, copper, etc., are non-magnetic. But are you sure? These materials are Diamagnetic Materials. A few materials might not have any magnetic moment, but others may have a high magnetic moment interaction. Diamagnetic materials are substances that are not attracted to any magnetic field. However, if you

Introduction: The idea of a circular loop as a magnetic dipole was found by Ampere. It was seen that a current-carrying circular loop forms similar magnetic lines of force as a magnetic dipole. It creates lines of forces that are circular towards the elementary portions of the current loop and almost straight towards the centre

The mechanism in physics using which some materials strongly attract each other is known as ferromagnetism. These materials usually include iron, lodestone, and other similar things. It is an important phenomenon of nature that is the cause of magnetism in materials.  Ferromagnetism is an essential phenomenon and ferromagnetic materials are widely used in various industries.

The Biot Savart Law is a numerical expression that exemplifies the magnetic field produced by a stable electric flow in the specific electromagnetism of physics. It says the magnetic field in the direction of the magnitude, length, direction, as well as nearness of the electric flow. This law is basic to magnetostatics and shows an

A solenoid is an electromagnet that has a tightly packed rounded coil in the form of a helix. The magnetic field is generated by passing the electricity, which induces magnetism. The bar magnet can be made to act as a solenoid. The rectangular type of magnet is said to be a bar magnet. It is

Introduction To better understand how forces worked on current-carrying wires, Ampere conducted several tests. Students must gain a clear understanding of both the electric and magnetic fields to comprehend Ampere’s law and its applications. Ampere’s law is defined as the line integral of a magnetic field intensity along a closed path is equal to the
