Magnetic field due to a current-carrying loop

An electromagnet is a device that consists of a magnetic core encircled by a coil through which an electric current is carried to magnetise the core. Wherever controllable magnets are required, such as in devices where the magnetic flux must be adjusted, reversed, or switched on and off, an electromagnet is utilised. Permanent magnets are […]

Magnetic Field  A magnetic field is a vector field in the presence of a magnet, an electric current, or a changing electric field in which magnetic forces may be observed. Magnetic fields, such as those found on Earth, induce magnetic compass needles and other permanent magnets to align in the field’s direction. Magnetic fields cause

In the Earth’s outer core, electric currents created by the motion of convection currents of a combination of molten iron and nickel are responsible for the generation of the magnetic field. Geodynamo is a natural phenomena that causes convection currents to be produced by heat escaping from the core of the earth. It is responsible

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.
