Googl Messages 111 Reaction score 1 Dec 12, 2010 #4 My teach is telling me that E=Q/4pi_r^2 is directly proportional to B/r^2 Does that make sense. The first formula is the formula used to find the electric field.

Googl Messages 111 Reaction score 1 Dec 12, 2010 #6 Yes it is the formula E from a point charge. What would the B/r^2 stand for in a solenoid experiment? I mean what would you use that for to find what? And what about B/r Thanks.
