PHYS 272 Lecture Notes - Lecture 36: Inductance
LECTURE APRIL 26 (THURSDAY)
MUTUAL INDUCTANCE
• Imagine a coil 1 with N1 turns and coil 2 with N2 turns
• Magnetic Field B is created. This is proportional to Current
•
•
•
• It does not depend on Current. It depends on Geometry
•
•
•

•
•
• The unit for Inductance is HENRY
SELF INDUCTANCE
As current changes, Flux varies and an EMF is induced. Lenz’s Law opposes the change in flux
producing Back-EMF.
