inductor: € == dI dt Lenz's Law: The induced EMF will fight the change in current through an - Ld where L is called the "inductance". The MKS units for inductance are Henry's (H). Note that L is greater than zero by definition. The minus sign tells you which direction the induced current will point. A) An induced emf of 20 mV is measured across a coil of 50 closely wound turns while the current through it increases uniformly from 0.0 to 5.0 A in 0.10 s. What is the self-inductance of the coil? Answer: L = 4.0x10-4 H
