1. The problem statement, all variables and given/known data
15. According to Lenz's law, the direction of an induced current in a conductor due to a change in the magnetic field near the conductor will be that which tends to produce which of the following effects?

a. Enhance the effect which produces it
b. Produce the greater heating effect
c. Produce the greatest voltage
d. Oppose the effect which produces it
e. There is no connection between the magnetic field and the flow of current

3. The attempt at a solution
My understanding is that this would be D. is this correct? any help is appreciated.

Oh, holy moderators, what is the rule for this kind of question?
For, lo!, no work has been submitted, but indeed, what sort of work can be submitted for a problem such as this?
Shall an equation alone suffice as "attempted solution"? Shall a detailed discussion of the equation be required torture? Or can we just say yes or no??

Right.

Lenz's law states exactly that, 'The direction of any induced current is such as to oppose the flux change which causes it'

Oppose is the key word here.

i'd say D, just because i see the words "oppose motion"

On my last physics test, i got a 96 because i forgot to mention Lenz's law. darn.
