 Presentation: Motional and Induce Emf; Self Induction By Group 6 ( part1)
Some contents from slides Motional EMF - The emf induced by the motion of a conductor across a magnetic field is called motional emf
- When a conductor is moved across a magnetic field an emf is induced between its ends.the emf of the moving conductor is similar to that of a battery
Electromagnetism induction: - The current produces in the conductor due to its motion in the magnetic field is called induced current
- If we change the resistance of the conductor by adding different resistors in the loop and move it in the magnetic field with the same speed every time , we find that the product of the induced current I and resistance R of the loop remains constant such that
- I x R=constant This constant is called induced emf
- This phenomena of production of the induced current and induced emf is called electromagnetic induction
Self Induction - The phenomenon in which a changing current in a coil induces an emf in itself is called self induction
 Presentation of the group 6 is divided into 3 parts on the bases of the Topic assigned to the group members
