Fleming's Right Hand Rule

-
Image
  Fleming's Right Hand Rule This law helps to find the  direction of induced current in the conductor when a conductor moves in the magnetic field. If we strech the fingers of right hand, then Thumb represents the direction of motion. Index finger represents the direction of magnetic field. Middle finger represents the direction of induced current in the conductor. Hope you found this post helpful. © Amogha A K. All Rights Reserved.

Fleming's Left Hand Rule

-
Image
  Fleming's Left Hand Rule It states that i f a conductor is placed in magnetic field and current is flowing through it, then it will experience a force which is mutually perpendicular to the field and current. If we stretch the fingers of left hand, then Index finger will represent the direction of magnetic field. Middle finger shows the direction of current. Thumb represents the direction of force.

Faraday's Law

-
Image
Faraday's law of induction/ Faraday's law It is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon known as electromagnetic induction . Faraday's first law of electromagnetic induction   Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. If the conductor circuit is closed, a current is induced which is called induced current. Faraday’s second law of electromagnetic induction It states that the induced emf in a coil is equal to the rate of change of flux linkage. Hope you found this post useful. © Amogha A K.
