Actually Van valkenburg writes in his world famous book NETWORK ANALYSIS, dB stands for <b>magnetic flux density </b> and he goes on to derive self inductance L equation from the same understanding. that is total flux=L x i

while checking the same equation in 12 standard physics book and some of the websites, it is found that dB stands for <b>magnetic field intensity (strength)</b>.

what is truth behind this controversy ?
