TA's must be prepared to provide a conceptual overview. Give the students the theory and tell them that the differential and integral forms can be used as the basis for two different measurements of the ambient field in the lab. Emphasis is on letting students figure out how to use the device to accomplish the measurement. text/html 2026-03-03T15:16:24+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.physlab-wiki.com/phylabs/lab_courses/phys-140-wiki-home/winter-experiments/faradays-law-lab/setup?rev=1772568984&do=diff Setup information for PHYS142 Faraday's Law lab.
