单项选择题
What is Lenz’s Law?
选项
A.a. The induced current in a loop is in the direction that creates a electric field that opposes the change in electric flux through the loop
B.b. The induced current in a loop is in the direction that creates a magnetic field that opposes the change in magnetic flux through the loop
C.c. The induced current in a loop is in the direction that creates a magnetic field that has the opposite direction to the original magnetic flux through the loop
D.d. The induced current in a loop is in the direction that creates a magnetic force that opposes the change in magnetic field through the loop

To approach this question, I will evaluate each option in turn and explain why it is correct or incorrect before identifying the true concept at work.
Option a: 'The induced current in a loop is in the direction that creates a electric field that opposes the change in electric flux through the loop.' This statement mentions an electric field opposing a change in electric flux, but Lenz's Law is about magnetic flux and the magnetic effects produced by the induced current. The focus is on magnetic flux, not e......Login to view full explanation登录即可查看完整答案
