Torque on a current loop in a magnetic field

An atom’s electron has its own orbital magnetic dipole moment and spins magnetic dipole moment that combines vectorially. In a material sample, the results of each atom combine with that of the other atoms. If all these magnetic dipole moments produce a magnetic field, we can say that the material has magnetism. There are general […]

Ferromagnetism takes its name from “ferrous,” implying iron, the primary metal known to show attractive properties to magnetic fields. Ferromagnetism is a magnetic behaviour displayed by specific materials like iron, cobalt, amalgams, etc. It is peculiar that these materials achieve super durable magnetism or get attractive powers. Likewise, it is portrayed as an interaction wherein

When ferromagnetic materials are exposed to a magnetic field, they become strongly magnetised in the direction of the field. Each atom of ferromagnetic material has a permanent magnetic dipole moment before an external magnetic field is applied. In the absence of an external field, the domains may randomly synchronise, resulting in a magnetic dipole moment

The magnetic forces of a material’s electrons will be changed when put in a magnetic field. Faraday’s law of magnetic induction describes this phenomenon. The magnetic properties determine how it responds to an external magnetic force.  Materials are classified into three types by their response to externally applied magnetic fields: diamagnetic, paramagnetic, or ferromagnetic fields.

Introduction A permanent magnet is a type of material with magnetic properties and creates its magnetic field. The materials which are strongly attracted towards a magnet under a certain distance are called ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. Some of them are naturally occurring, like loadstones. A ferromagnetic material is divided into

Introduction As we all know, magnetization is caused by the presence of a magnetic moment. This is caused by the movement of electrons within the atoms themselves. An external magnetic field induces a response in a substance, which is represented by its net magnetization. Furthermore, it takes into account any imbalanced magnetic dipole moment that

What is Magnetic Moment? The production of a magnetic field (by a magnet) using its magnetic strength and orientation properties is called magnetic moment—the magnetic moment inside the magnet points toward its north pole. The SI unit of magnetic moment is ampere-square metre (Am²). These are the same dimensions that current×area or energy/magnetic flux density

The electron magnetic moment, or more properly the electron magnetic dipole moment, is the magnetic moment of an electron induced by its intrinsic spin and electric charge features in atomic physics. A magnetic dipole is a small magnet with microscopic to subatomic size that is analogous to an electric charge flow around a loop. Magnetic

Magnetic flux is the number of magnetic field lines or magnetic lines of force passing through a surface. Thus, in simplified terms, the magnetic flux through some surface is proportional to the number of field lines passing through that surface. The magnetic flux across a surface is defined as the electric field flux used with

Iron items are attracted to the poles of a bar magnet. One end of the magnet is the north pole, the other one is the south pole. Magnetism is generated by the force created by magnets, thereby further creating fields that cause diverse metallic objects to attract or repel one another. Particles that are electrically
