Magnetic field due to a current-carrying loop

Introduction: In 1820, HC Oersted proved that electric current creates a magnetic field around it. Michael Faraday observed this and believed that if an electric current can create a magnetic field, then a magnetic field can also create a current. In 1831, Faraday showed the world that if a magnet is moved inside a copper […]

The term magnet refers to any material that creates a magnetic field that either attracts or repels other magnetic materials in physics. Whenever a magnet is polarised, it has two poles, which are referred to as the north and south poles. These two poles are always together and cannot be separated; therefore, when we freely

There is a magnetic field surrounding an electrical conductor when the flow of current happens through it. The strength of the magnetic field runs in proportion to the current flow. This remains so till there is the flow of current through the conductor, when the flow of current stops the magnetic field disappears. The direction

Solenoid and Toroid are magnetic field-producing devices that use the magnetic effect of electricity. Its key benefit over traditional magnets is that the magnetic intensity may be changed by adjusting the amount of electric current flowing via them. They can be switched on and off, as permanent magnets, making them excellent for a variety of

The circular motion of electrons plays a significant role in the process of magnetism. The atom’s magnetic moment occurs due to the vector sum of spin and orbital magnetic moment. On the basis of magnetic properties, magnetic substances are further classified into three categories. These include Paramagnetism, diamagnetism and ferromagnetism.  Today, in this article on

When a current is flowing through a wire, a magnetic field will be created around the wire to protect it. The magnetic field forms circular loops around the wire and the strength of these loops decreases as the distance between the wire and the observer increases. In order to determine the direction of the magnetic

Magnetism is a wide-known and widely applied concept that can be explained with the help of the circular motion of electrons. The electrons moving around in a circular orbit inside an atom exhibit the same properties as circular coil-carrying current. This circular motion of the electron in the orbit gives rise to the orbital magnetic

In electromagnetism, permeability is a measure of the amount of magnetization that a material acquires as a result of being exposed to a magnetic field. The Greek letter μ is commonly used to signify permeability in mathematical notation. Oliver Heaviside created the phrase in September 1885, and it has been in use ever since. It

Meissner Effect is the effect that converts a material from a normal state to a superconducting state. When a material is called below a specified temperature at which the magnetic field from the interior of the material is exploded, then this material is transformed into the superconductor. This phenomenon is called the Meissner Effect. The

Introduction The term “magnetism” is derived from an island in Greece, which was then called Magnesia. The island contained deposits of magnets back in 600BC. Hans Christian Oersted made an observation that later indicated the relationship between electricity and magnetism. While performing experiments, he observed that the magnet gets deflected if kept near wires carrying
