Magnetic Effects of Current

The French physicist Louis Eugene Felix Neel invented ferromagnetic materials or substances. He also brought forward the point that the atoms present in those materials are examples of ferromagnetic materials and can arrange themselves in domains, which is the name given to small groups of ferromagnetic materials. Every domain has a different magnetic dipole moment.  […]

Materials that are freely magnetised by magnetic fields are called Diamagnetic Materials. In this case, magnetization occurs in the opposite direction to the magnetic field. Diamagnetism is displayed in these materials. Diamagnetic Materials are repellent to the external magnetic field. The orbital angular momentum of electrons in an atom is determined by their rotation around

An electric current loop experiences an induced force inside a magnetic field. If the flow of the current and the magnetic field lines are perpendicular to one another, we can apply Fleming’s Left-hand Rule to get the direction of the force on the current loop. If the forces are of identical magnitude, opposite in direction,

The magnetic dipole can be defined as small magnets of subatomic or microscopic dimensions that show the characteristics and properties of an electric charge around a loop. The magnetic dipole can be called an analogue of the electric dipole. This means the magnetic dipole behaves like an electric dipole. But the analogy is not flawless.

Introduction We know that if an electric dipole is placed in a uniform electric field, it will feel some amount of torque; likewise, if a magnetic dipole is placed in a uniform magnetic field, a net torque will be acted on it. We represent magnetic flux density with ‘B’ and magnetic dipole moment with ‘M’.

Introduction   In physics, the uniform magnetic field applied to the current loop does not exert any net force. But one thing it does is exert the torque on it. Before we explain torque experienced by a current loop, let’s know what the torque is. Torque, also referred to as the moment of the force, is

When a moving charge interacts with a magnetic electric field, there are a lot of changes happening in moving charges and magnetic electric field. Before knowing the charges, we need to know that most of the magnetism is caused by the current, which means magnetism is caused by the flow of charge and magnetic fields

A magnetic dipole is an arrangement of two equal and opposite magnetic poles separated by a little distance. The product of a magnetic dipole’s pole strength and magnetic length is the magnetic dipole moment. It’s a vector quantity that goes from the S-pole to the N-pole. Ampere discovered that the magnetic line of force distribution

Defining permanent magnets Magnets are metals that develop an invisible force field around themselves. These invisible fields are called magnetic fields. A magnetic field attracts ferromagnetic materials, including iron, steel, nickel, cobalt, etc.  The field is concentrated at the ends of the magnet, called poles. A magnet comprises two poles: the north pole and the

Magnets are metals or rocks that create a magnetic field around them. This invisible field is responsible for attracting other magnets and some metals. Many magnets also exist in everyday life, such as fridge magnets, magnetic toys, medical processes, etc.  Some different shapes of magnetic include bar magnets, horseshoe magnets, cylinder magnetic, sphere magnets and
