Meir Achuz Posted August 19, 2005 Share Posted August 19, 2005 The magnetic field on the z axis of a solenoid (in Gaussian units) is:B=[2\pi(N/L)I/c][sin A_2-sin A_1]' date=' where A_i is the angle between a line perpendicular to the axis of the solenoid at one end and a point on the z axis. If you write this in terms of z and expand, you can use Legendre polyomials to find the field off the axis and the dipole moment of the solenoid.[/quote'] I thought this was a complete answer.

labview1958 Posted August 27, 2005 Share Posted August 27, 2005 I do not know much about Legendre Poynomials. Can you expand the equation a bit in plain english? Link to comment Share on other sites More sharing options...
