Magnetic field due to a current loop, solenoid

Introduction In 1934, E.O. Lawrence and M.S. Livingston invented the cyclotron, a device known to accelerate the charged particles or ions to high energies. For the acceleration of the particles, both electric and magnetic fields are used. During the insertion of charged particles in a cyclotron, the static magnetic field and direction of motion are […]

Earth’s magnetic field, otherwise also called a geomagnetic field, is a magnetic field that is associated with planet Earth. This magnetic field spreads from the interior of the Earth to the space above. In outer space, it proceeds to interact with the solar winds and charged steam particles that are given out by the sun.

Until the 19th century, the only known concept of magnetism was ferromagnetism. Additionally, the idea of magnetism revolved around the concept that certain materials would attract specific materials when brought in contact with magnets, commonly iron (ferrous). When studying the relatively new field of electric currents, it was discovered that moving currents induced magnetic fields.

In 1820, it was discovered that electricity and magnetism are intimately related to each other. Besides this, Danish physicist Hans Christian Oersted observed that the current in a straight wire produces a slight deflection in a nearby magnetic compass needle. The deflection increases in the compass when it is brought closer to the current wire

Biot Savart’s Law is the fundamental of magnetostatics. Therefore, it plays a crucial role in the field of electromagnetism. The law describes the equation between the magnetic field produced due to the flow of a constant electric current. The law is useful for knowing the magnetic field’s direction, length, and magnitude, and the proximity of

Lenz’s law is more or less based on Faraday’s law of guidance. Faraday’s law states that electric current in a conductor is induced by magnetic fields that are constantly changing. Lenz’s law indicates the direction of this induced current. This opposes a change in the magnetic field that created it. The change is indicated by

The relation between the electric current passing from the loop and the integrated magnetic field of a closed loop is defined by the Ampere Circuital Law. The Law defines the proportionality between the magnetic field developed in space around an electric current and the electric current at the point of source. The law states that

The magnetic field of a current-carrying conductor can be simply given by the current flowing through the conductor μₒ  times. The stationary charge produces the magnetic field proportional to the magnitude of the charge but the moving charge produces a magnetic field proportional to the current. The main drawback to Ampere’s Law is that differential

Introduction  Maxwell discovered a discrepancy in Ampere’s law and proposed the need for displacement current to correct it. This displacement current is caused by a changing electric field and is generated by and acts as a magnetic field source in the same manner that conduction current does. Displacement Current The displacement current is the rate
