It doesn't specify the rate of decrease. It just states, "If bothmagnetic fields begin to decrease in magnitude, what is the direction of the induced current in the loop? Explain with Lenz's Law." The phrase at the LHS-bottom of the image is just Part B.
Awesome! I think I'm really starting to understand this. Just one more question just to fully nail this into my knowledge bank. An induced field is just a magnetic field, and an applied field is the electromagnetic field that is generated with a changing induced field?
So, Lenz's Law states the direction of the induced current is such that the induced magnetic field opposes the change in the flux (from my book). Because the changing flux is into the page, the current is counter-clockwise, opposing the changing flux. The right hand rule, curling the fingers...
This is a continuation of a previous thread in which I was informed my TA was mistaken on an aspect of magnetism. This thread is just to verify another problem within the homework is correct. Other threads will be posted to continue.

A) What is the magnetic flux...
Ok. That's what I originally thought. Now I know why I'm having such a hard time in this class, because one person says one thing and another says another, and it just really confuses me. I'm going to start going to another TA for guidance.
I'm also questioning my other problems now. If...
Yes, the X's denote into the page. Dots denote out of the page. I originally had it opposite to what I've posted here, but the TA said it was wrong. So I changed it to the above, and she approved. It's a bit confusing now, but i figured the into the page meant the field was decreasing, but...
So the main reason I'm posting about this problem is that one of the teaching assistants helped me with this problem, but a buddy of mine got something different on part A and part B (Assess). So I wanted to post up here and see what you guys say.

I apologize for the late reply. My truck's oil cooler o rings started leaking profusely and I had to rebuild my oil cooler.
Never mind. I answered my own question by going back and looking through my answer, realizing I calculated the potential energy.
Anyways, thanks again everyone. I...

I really appreciate both your help. TSny, when you say the value of the potential energy is small, are you reffering to the 7.0 nC charge for the charged particle...
ah. This is where my math skills are starting to show.
It appears I went the hard route and attempted to put the v2 on the left side the "=" when it could've remained on the right and rather move the 2.5x10-6 to the left.
If I were to manipulate the equation in this fashion...

A) Calculate the electric potential at point A.
B) If a small charged particle with a mass m=5.0 mg and charge q=7.0 nC is released from rest at point A, what will be its final speed vf

Thank you, gentlemen!
Mark, I'm a huge motorcycle fan! if you ever want to let go of the flathead or panhead, let me know! haha. Those are beautiful bikes. Before I graduated from the community college in Tulsa, I finished up a project, but sold it before moving out here to Fayetteville...
