Magnetic field due to a current loop, solenoid

Introduction to Ampere’s law Ampere’s law is one of the significant laws of electromagnetism, which states that “The attractive field generation due to electric flow becomes relative to the size of the electric flow with a consistent proportionality equivalent to the permeability of free space”. This law allows us to keep an appropriate extension to […]

A permanent magnet is a type of material that has its own magnetic properties and creates its own magnetic field. Materials such as iron, steel, nickel, cobalt etc., that are strongly attracted towards a magnet within a certain distance are called ferromagnetic. Some of them are naturally occurring, like loadstones. A ferromagnetic material is divided

Paramagnetic substances get weakly magnetised or tend to get weakly magnetised along the direction of an externally applied magnetic field. Upon removing the magnetic field, the substance subsequently gets non-magnetized. They tend to have a permanent magnetic moment or a permanent dipole throughout. They have unpaired electrons in them. The net dipole in these substances

What are Eddy Currents? Eddy currents are produced due to changes in the magnetic field. In other words, we can say that when the magnetic flux is flowing inside a coil, eddy currents are formed. These currents are created by the concept of electromagnetic induction. They are always present in closed loops. This is the

Magnetism is the force that acts on the area around a magnet or moving electric charge where there is magnetism. Magnets, electric currents, and changing electric fields can produce magnetic fields in their vicinity. Electromagnetic fields are produced by moving electric charges and the intrinsic uniform magnetic field moments associated with elementary particles’ fundamental quantum

In 1820, French scientist Christian Oersted observed that the compass needle deflected from its initial direction, which is the north-south direction, in the presence of current-carrying wire. Oersted’s experiment is the first, which describes that current-carrying wire produces a magnetic field. The setup requires a planar coil of wire to deflect the magnetic needle vigorously

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
