Magnetic field due to a current-carrying loop

Whenever a charge is moving, it’s suffering from a field of force. It creates a force, which is normal to its movement. This property of charge covers plenty of fields, as an example, this phenomenon is employed within the making of motors which successively are useful for creating mechanical forces. These forces are represented by […]

Introduction In this article, you will find all the essential concepts related to the force on a current-carrying conductor. We have introduced the concept of force on a current-carrying conductor, Characteristics of Magnetic Field, Magnetic Field, Magnetic Field due to current-carrying wire, and Magnetic Force. Force on a current-carrying conductor is given by F =

Introduction In 1820, HC Oersted proved that electric current creates a magnetic field. 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 coil, very

Introduction Experimentally it has been observed that when two current-carrying conductors are placed in the vicinity when having the opposite direction of current flow, there is an observable force between them that pulls both the current carrying conductors closer. Also, the conductors repel each other when the direction of the current flow is the same.

You must be familiar with the famous compass needle deflection experiment that forms the basics of magnetism. Whenever a compass is placed near a current-carrying conductor, the compass needle shows a deflection. You will find various shapes of current-carrying conductors. The shapes and structures of these conductors are the deciding factors for the magnetic field.

Ferromagnetism is a scientific phenomena in which certain electrically uncharged materials attract others strongly. Lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, both occurring in nature, have the capacity to develop such appealing properties and are commonly referred to as natural ferromagnets. They were discovered about 2,000 years ago, and all early scientific

Introduction: Electric current creates the magnetic field in an electromagnet. A wire looped around a coil is the most common building block of an electromagnet. Electromagnetism occurs when current flows through the wire, creating a magnetic field in the coil’s centre. Electromagnets are made by winding a wire around a soft iron core in a

Introduction Electric current creates the magnetic field in an electromagnet, a special magnet. Wire looped around a coil is an electromagnet’s most common building block. Electromagnetism occurs when current flows through the wire, creating a magnetic field in the coil’s center. When the current is switched off, the magnetic field dissipates. To increase the magnetic

When the magnetic field varies continuously as a result called electromagnetic induction. In simple language we say that, whenever the number of magnetic lines of force passing through a circuit changes,EMF is produced in the circuit. If the circuit is closed, a current flows through it. The EMF and the current produced are called induced

An electromagnet is a device which consists of a magnetic core encircled by a coil by which an electric current is carried to magnetise the core. Whenever controllable magnets are needed, such as in devices where the magnetic flux must be adjusted, reversed, or switched on and off, an electromagnet is employed. Magnets Magnets are materials
