I get the same thing as you...apparently I wasnt paying atttention before.

Crap, so the change of B would be two so if I put emf=(2pie(.15^2)/1.5=.942 volts and then current would be .942/2=.0471 ohms Does the answer look good now?

OK I am back. It turns out this problem was on the test with one variation the radius went to 15cm. I used faradays law but got the answer wrong here is what I did. emf=(pie(.15^2)/1.5=.0471 volts and then to find the current I=V/R=.0471/2=.0236

Here is a question I have on a practice exam that I am having a littel trouble with. A plane loop of wire consisting of a single turn if radius 5cm is perpendicular to a magnetic field that increases uniformly in magnitude from 0.5T to 2.5T in 1.5 seconds what is the resluting indiced current if...

nevermind I aced it. I was making it a little more confusing then it actually was. Thank you for the help.

so I read that and still confused

Line Integral and Magnetism Help! Here is a problem given to me as a takehome quiz I am having trouble even starting being that I missed that day we went over line integrals. Any hints or tips are much appreciated. http://ez-files.net/download.php?file=4ec07c5df1e8223123523fb11f038d39"

Thanks for the help I got them figured out now...I hope

My prof gave us a question to take home and examine and review because he had to leave on urgent family matters so as a result we had to teach a chapter to ourselves about thermodynamics. Inside the chapter is a section on Entropy which I am getting really hung up on, but anyways here is the...
