WebWhat is flux in transformer? In a transformer, the magnetic flux created by the primary coil induces a current in the core. This occurs in order to oppose the charge that produced the magnetic flux (Lenz's Law). The currents flowing in the core are called eddy currents. These currents produce heat, using up energy and so causing inefficiency. WebThe “Transformer Equation” (Faraday’s Law) • B in tesla, Ae in m2, f in Hz – Modern SI units • The saturation flux density, Bmax, determines the maximum volts per turn that can be applied to a given transformer or inductor winding at a given frequency. B A f N E =4 ⋅ e ⋅
