EI - Q. based on Spec

  1. What is the definition of magnetic flux and what does the formula ( \Phi = AB \cos \Theta ) represent?

  2. What is flux linkage and how is it mathematically expressed?

  3. What are Faraday's laws of electromagnetic induction?

  4. What is Lenz's law, and how does it relate to the direction of induced emf?

  5. How can you apply Faraday's and Lenz's laws to set up the equation for emf as the rate of change of flux linkage?

  6. Explain how an induced emf is generated in a linear conductor that moves at right angles to a uniform magnetic field.

  7. How does the position of a coil rotating in a magnetic field affect the instantaneous emf induced?
