Change in magnetic flux formula

WebDec 2, 2024 · A changing magnetic flux induces an EMF. Now, if we want to use your version of the above equation, we should take it to mean the following: If I increase the number of turns in my coil, then in order to get the same EMF I would need a smaller change in flux through one turn per unit time. WebAs per the definition of flux linkage, we know the general formula for finding flux linkage is: λ = N/π. Where, λ is the flux linkage. N is the number of turns. Φis the magnetic flux. Supposedly, a circular coil has 42 turns and is kept in a magnetic field. The magnetic flux is 101 * 10 -7 T.
