Magnetic field due to a current loop, solenoid

Compass needles are oriented roughly northward over a large portion of the Earth’s surface. Despite this, due to the intricate nature of the Earth’s magnetic field, there are only a few sites on the planet where a compass needle will always point north. Using a compass, you can align yourself with the horizontal component of […]

Magnetic force is the force of attraction or repulsion which acts between the electrically charged ions because of their motion. This force can be seen in the current-carrying wires, which are parallel to each other and enough in length. The force of attraction or repulsion between the two similar wires is the same whether the

In electromagnetism, displacement current is a phenomenon similar to an ordinary electric current proposed to explain magnetic fields created by altering electric fields. Ordinary electric currents, known as conduction currents, create an associated magnetic field in the current area, whether constant or variable. Because magnetic fields have long been related to currents, the projected magnetic

Eddy current in physics is also known as the Foucault current. Conductors that are triggered by a constantly changing magnetic field within them can generate eddy currents. In other words, eddy currents are closed loops of electric current induced by a changing magnetic field. Faraday’s law of induction forms the basis of Eddy Current. It

Paramagnetic solutions get magnetised very faintly in the direction of any externally applied magnetic field. They lose their magnetic properties when the field is removed. They tend to orient themselves where they feel the magnetic field more strongly. Paramagnetic liquids have a permanent magnetic moment or dipole because of the presence of an unpaired electron

The generation of the magnetic field in the matter is contributed to the spinning motion of the electrons and the interactions between them. The response of different materials to magnetism forms the basis of the classification of matter into paramagnetic, diamagnetic and ferromagnetic. All materials have some sort of magnetic permeability in them, some have

Bar magnets are just a type of magnets that are rectangular. Bar magnets bear the same properties as a magnet. We also hypothesise that our earth contains a massive bar magnet inside its core. The north and south poles of a magnet are determined to correspond to the poles of the earth’s magnet. A solenoid

An eddy current is a type of current that is produced due to changes in the magnetic field. In other words, when a magnetic flux is flowing inside a coil, eddy currents are subsequently formed. These currents are created by electromagnetic induction. They are always present in closed loops. Eddy currents produce a magnetic field

The concept of displacement current may be traced back to a well-known scientist named James Clerk Maxwell. Maxwell is well recognised for what is known as Maxwell’s equations. The four equations, when combined, create an elegant method of explaining the basics of electricity and magnetism. We shall be particularly interested in one of these equations,

Eddy currents are produced due to changes in the magnetic field. They are created when a conductor moves through a magnetic field or when the magnetic field around a stationary conductor varies. In other words, anything that causes the conductor to experience a change in the direction or intensity of a magnetic field can produce
