The negative sign in Faraday's law expresses which law?
AOhm's laws
BGauss's law
CJoule's law
DLenz's law
Answer & Solution
Correct answer: D. Lenz's law
1. The magnitude of the emf comes from the rate of change of flux.
2. The sign carries the direction information.
3. That direction rule is Lenz's law.
4. So the answer is Lenz's law.
