1. 25. EMI 1We kickstarted last week with the topic of Electromagnetic Induction and we learnt that this topic is, in essence, the reverse of electromagnetism, in which now we are trying to generate electricity from magnetic field instead. So here's some important pointers on what we have learnt: 1. To generate induced EMF, there must be a change in the magnetic flux linkage (MFL) between the magnet and the coil. 2. Faraday's law states that the induced EMF is directly proportional to the rate of change in MFL. 3. Lenz's law is concerned with the direction of induced current, in which the induced current will flow in such a way as to produce a magnetic effect that will oppose the change in MFL (or motion of the magnet). 4. We can generate induced EMF as well by using a straight conductor to cut through magnetic field lines.
