![]() Substitute value of B and ϕ is above formula L Where B = magnetic field =( MLT- 2) /LT -1AT = MT -2A -1 Where € = induced EMF = work done / electric charge with respect to time = M. ![]() The dimension of this can be defined as the ratio of potential difference to the rate of change of current. This phenomenon is referred to as mutual inductance.Ĭonsider the total inductance between the two coils be L since M = √(L1L2) = L When two or more coils are linked together magnetically with the same magnetic flux, then the voltage induced in one coil is proportional to the rate of change of current in another coil. It is taken from the American scientist Joseph Henry, who explained the phenomenon of two coils. ![]() The SI unit of mutual inductance is Henry. The amount of inductance produces the voltage of one volt due to the rate of change of current of 1Ampere/second. L = length of the coil in meters Unit of Mutual Inductance
