What is emf?
Question asked by: stephy
EMF stands for electromagnetic field, and it is a forcefield around objects.
At one stage electricity and magnetism were though of as separate forces, but experiment showed that they are related, and Maxwell was able to produce some brilliant equations to unite mathematically for the first time the two forces, hence they were known as electromagnetism.
For instance if you put iron filings around a magnet you see them line up showing that the magnetic field is there even though it is invisible.
