Magnetic Effects of Current

Magnet: Magnetic field and magnetic field lines, Magnetic field due to a current-carrying conductor, Right-hand thumb rule, Magnetic field due to current through a circular loop. Magnetic field due to current in a solenoid.A magnet is an object that attracts objects made of iron, cobalt and Nickel. Magnet comes to rest in the North-South direction when […]

Introduction A part of the magnetic field that arises from the external current rather than the intrinsic properties is known as magnetic field intensity or magnetic field strength or magnetic intensity. Also, the area around the magnet or the area in which the magnetism effect is felt is the magnetic field. In a wire that

Introduction Magnetic Elements are free-floating magnetic needles that come to rest roughly around the geographical north-south axis. This behaviour demonstrates that the Earth operates as a massive magnetic dipole; its magnetic poles lie close to its geographical ones. Because the magnetic needle’s north pole approximates geographic north (NG), the magnetic pole near it is the

The magnetic declination and inclination are essential properties of the earth’s magnetic field. The predominant source of the magnetic field is the dynamo effect inside the planet. The dynamo effect is a naturally occurring phenomenon in which heat from the earth’s core produces a series of electric currents, which creates a magnetic field. A three-dimensional

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
