Wheatstone Bridge Working Principle

Wheatstone Bridge Working Principle   Wheatstone devised a bridge-arrangement of resistances by which the resistance of a given conductor can be determined. This arrangement is called the ‘Wheatstone bridge‘.   In the arrangement, four resistances are so connected as to form a parallelogram. In one diagonal of this parallelogram is connected a galvanometer and in …

Diamagnetic | Paramagnetic | Ferromagnetic Materials

Diamagnetic Materials   These materials are feebly repelled by a magnet. When placed in a magnetizing field, they are feebly magnetized in a direction opposite to that of the field. Thus, the susceptibility of diamagnetic material is small and negative.   Further, the flux density in a diamagnetic material placed in a magnetizing field is …
