Homework Statement
Determine an equation to calculate the flux density at the center of a range of current loops encircling each other.
Homework Equations
The equation for the magnetic flux density at the center of a current loop is
mu*I / (2*r)
The Attempt at a Solution
I assumed I could just integrate the above equation over a range of radii as follows:
b
[tex]\int[/tex](mu*I / (2*r)) dr = (mu*I/2)*-ln(a/b)
a
Have I done this correctly or do the magnetic fields not add this way? Please help!
PS. How on Earth do you use the maths tools to write equations in these posts.
