Lenz's Law: Direction of Induced Current

AI Thread Summary
According to Lenz's Law, the direction of an induced current in a conductor due to a changing magnetic field is to oppose the effect that produces it, making option D the correct answer. Participants in the discussion express confusion about the requirements for submitting solutions, questioning whether a simple answer suffices or if a detailed explanation is necessary. The importance of Lenz's Law is emphasized, particularly the concept of opposition to flux changes. One contributor reflects on their previous exam experience, highlighting the significance of mentioning Lenz's Law in physics problems. Understanding Lenz's Law is crucial for accurately determining the behavior of induced currents in electromagnetic contexts.

Homework Statement


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

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??

edit: WakeJosh, I have the same question about your other thread.
 
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.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
