Induced Current

Motional EMF

Motional EMF When a conductor is moved across a magnetic field, a potential difference is setup across its ends. This potential difference is called ‘Motional EMF’. Consider the bar in the figure below. It has length l and moves at speed v to the right in magnetic field B, which is directed into the page. The field exerts a magnetic force Read more about Motional EMF[…]

Biot – Savart Law and Its Applications

Biot – Savart Law and Its Applications Two French physicists, Jean Baptiste Biot and Felix Savart derived the mathematical expression for magnetic flux density at a point due a nearby current carrying conductor, in 1820. Viewing the deflection of a magnetic compass needle, two scientists concluded that any current element projects a magnetic field in the Read more about Biot – Savart Law and Its Applications[…]

Parallel Plate Capacitor

Parallel Plate Capacitor

Parallel Plate Capacitor Parallel Plate Capacitors are the type of capacitors which are formed by arrangement of electrodes and insulating material (dielectric). The two conducting plates act as electrodes which are separated by a dielectric between them. The two plates of parallel plate capacitor are of equal dimensions and is connected to power supply. The Read more about Parallel Plate Capacitor[…]
