Unit 3

This document discusses magneto-static fields and provides examples such as transformers, microphones, telephone bell ringers, and television focusing. It also discusses the field due to a current carrying conductor and Ampere's circuit law, which is one of Maxwell's equations stating that the line integral of the tangential component of H around a closed path equals the net enclosed current.

Magneto-static Fields
Examples
• Transformer
• Microphones
• Telephone bell ringers
• Television focusing
Field due to a current carrying conductor
Problem:
Ampere's Circuit Law-Maxwell's
Equation
Ampere's Circuit Law—Maxwell's Equation

• Ampere's circuit law states that the line integral of the


tangential component of H around a closed path is the same as
the net current Ienc enclosed by the path.
In other words, the circulation of H equals Ienc
