Circuit Analysis Accounts For Magnetic Fields

by Ken Yang, Senior Member of the Technical Staff, Maxim Integrated Products Inc., Sunnyvale, Calif., Power Electronics Technology, Nov 01 2004

Focus:
Electric motors, transformers, and inductors generate time-varying magnetic fields that can induce noise into electronic circuits. To account for this noise during circuit analysis, Faraday's law must be invoked alongside Ohm's law and Kirchoff's law.

What you’ll learn:

• How to account for effects of a time-varying magnetic field on electronic circuits when performing circuit analysis
• How to extend Ohm's Law and Kirchoff's Voltage Law to account for noise currents induced by a time-varying magnetic field
