Ampere's Law is extremely useful in calculating the magnitude of magnetic fields when there is symmetry in the application. Remember that Ampere's Law is stated as
When applying Ampere's Law we must use an Amperian Loop which is a closed path with a specified direction to its circulation. Remember that µ_{o} equals 4p x 10^{-7} Tm/A.
The following formulas are based on Ampere's Law: |
