Electro-magnetic Induction Electro-magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. It is the basic principle…

Hall potential or voltage: If a magnetic field is applied perpendicular to the flow of current, then a potential or voltage is created normal to…

One ampere: Ampere or amp (symbol: A) is the unit of electrical current. The amount of current flowing in each of the two parallel wires…

One weber: Number of flux that charges in a coil per second for which 1-volt potential difference generates in that coil is called 1 Weber.…

One Tesla: If 1 coulomb of charge is in the motion perpendicular to the direction of magnetic field with a velocity of 1 ms-1 and…

Magnetic field lines: Magnetic field lines are some closed curve lines drawn in the magnetic field and a tangent drawn on any line at a…

Use of Temporary magnet Temporary magnets are prepared from soft metals, and only preserve their magnetism while close to a permanent magnetic field or electronic…

Use of Permanent Magnet A magnet produced by cast iron, nickel, and the alloy of iron is called permanent magnet. The magnets which are used…
