Ampère's Law


Turn on the Ampere's Law function of the EM Field software from the menu bar.


Task #1With the mouse down, trace along (approximately) one of the magnetic field
lines that represents a closed path (you should form a closed curve).
AL 1) What result do you get? How do you explain that result? Capture an image
of this result and paste it into your Word document.

Task #2Complete another closed patharound a collection of line currents.
AL 2) What results do you get for each different closed path? Explain

why.

Task #3


If you were to trace a closed path that includes all of the line currents, what
answer would you predict for such a path?

AL 3)Trace out such a path. How does the result compare with your predictions?
Explain the result you get. Capture an image of this result and paste it into
your Word document.
