Mutual Inductance Mutual inductance is a fundamental concept in electromagnetism that describes the relationship between two adjacent conductors or coils. It is defined as the ability of one coil to induce an electromotive force (EMF) or voltage in the other coil when the current flowing through the first coil changes. Here are some key points…
Lenz Law Lenz’s Law is a fundamental principle in electromagnetism that describes the direction of an induced current or electromagnetic force in a conductor when it is exposed to a changing magnetic field. Lenz’s Law is named after the Russian physicist Heinrich Lenz, who formulated it in 1834. The statement of Lenz’s Law is as…
Faraday’s law Faraday’s law, named after the British scientist Michael Faraday, describes the relationship between a changing magnetic field and the induced electromotive force (emf) in a conducting loop or circuit. The law consists of two key statements: Faraday’s law forms the basis for the operation of numerous devices, such as electric generators and transformers.…

Current loop as a magnetic dipole A current loop can be considered as a magnetic dipole due to its magnetic properties. When electric current flows through a closed loop, it generates a magnetic field around it, similar to a bar magnet. This magnetic field is responsible for the loop’s behavior as a magnetic dipole. Here…
Cyclotron A cyclotron is a type of particle accelerator that uses a combination of magnetic and electric fields to accelerate charged particles to high energies. It was invented by Ernest O. Lawrence in 1932 and has since become an essential tool in various fields of research, including nuclear physics and medical applications. Here’s a more…
Biot-Savart Law The Biot-Savart Law is a fundamental principle in electromagnetism that describes the magnetic field produced by a steady current in a conductor. It is named after Jean-Baptiste Biot and Félix Savart, who formulated the law in the 19th century. The Biot-Savart Law states that the magnetic field, represented by B, at a point…
