Fleming’s Left Hand Rule & Fleming’s Right Hand Rule

J. A. Fleming introduced two important rules to determine the direction of motion or force in case of motor and the direction of induced current in case of a generator. These rules are called as Fleming’s left hand rule (used for motors) and Fleming’s right hand rule (used for generators) respectively. When a current-carrying conductor … Read more

Maxwell’s Right Hand Grip Rule And Right Handed Cork Screw Rule

When the current flows to the conductor, a magnetic field is produced around it. The nature of magnetic field around a straight current carrying conductor is like concentric circles. The center of these concentric circle is axis of the current carrying conductor. The direction of these circular magnetic lines is dependent upon the direction of flow … Read more

Faraday’s Law And Lenz’s Law Of Electromagnetic Induction

In 1831, Micheal Faraday formulated two important laws on the basis of certain experiments that shows a relationship between the electric circuit and magnetic field. These laws are called Faraday’s laws of electromagnetic induction. Faraday’s First Law According to Faraday’s First Law, Whenever a conductor is placed in a varying magnetic field, an EMF is … Read more

Kirchhoff Current Law and Kirchhoff Voltage Law

There are some simple relations between currents and voltages of different branches of an electrical circuit. These relations are determined by some elementary laws that are known as Kirchhoff laws or more exactly Kirchhoff Current and Voltage laws. These laws are first derived by Gustave Robert Kirchhoff and therefore these laws are also called as Kirchhoff … Read more
