Relevant equations Frequency f= Bq/2πΜ 3. The attempt at a solution Β=(2π×3.3 ×10^ -27 ×12 ×10^6)/1.6×10^ -19 = 1.55Wb/m2 .Have i done this right? Why did they give me the dee radius if didn't need it?   Oct 30th 2014, 07:06 PM   #2

(shrugs) The problem writers do that just to screw you up a bit. I can't think of a reason you would need to use this data to solve the given problem.

Your equation is correct and the numbers come out like you say.

You don't trust your calculator?
