Question
I seem to get confused on manipulating the formulas and being able to solve for each variable in that formula...
so for the following formulas could you please show me how to reorganize each formula so that I can sole for each variable? The following formulas are from magnetism, and induction.
F=q(VxB)
F=qvBsin(theta)
r=mv/qB
F=ILBsin(theta)
B=(U0)(I)/(2pi)(r)
E=vBL
Flux=BA=BAcos(theta)
E= - (change flux) / (change t)
What I'm asking is for example how would you rearrange the formula to find r in...
B= (U0)(I) / (2pi)(r)
Explanation / Answer
B = u0 I/(2 pi r)
multiply both sides by r
B r = u0 I/( 2 pi r) *r
the r will cancel on the right
B r = u0 I/( 2 pi)
divide both sides by B
r = u0 I/(2 pi B)
