Magnetic Effects of Current

The Earth’s Magnetic Field is why free-floating magnetic needles come to rest roughly along the geographical north-south axis. It demonstrates that the earth operates as a massive magnetic dipole, with its magnetic poles located close to its geographical poles. Because the magnetic needle’s north pole approximates geographic north (NG), the magnetic pole near NG is […]

In our day-to-day life, we encounter different magnets like bar magnets, horseshoe magnets, sphere magnets, disc magnets, cylindrical magnets, and many more. We all know that these magnets have two poles: the north and south poles. These magnets are called permanent magnets. Their magnetic force stays for a long time until the materials from which

Almost everyone is aware of the attraction and repulsion of magnets. But what many may not know is how magnets are formed and why they attract or repel each other.  Magnets work on the magnetic field they produce; the biggest example is the Earth, which keeps solar winds from damaging its protective layers. An electromagnet

Substances that are freely magnetised by magnetic fields are called diamagnetic substances. In this case, magnetization occurs in the opposite direction to the magnetic field. Diamagnetic substances are repellent to the external magnetic field. Their rotation around the nucleus determines the orbital angular momentum of electrons in an atom. In the case of a diamagnetic

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
