Analytical calculation of magnetic flux lines in 3-D space

We propose a new analytical method for computation of magnetic flux lines in 3-D space. Using the results obtained from finite element analysis and the magnetic flux line equation in 3-D space, the sequence of line segments that construct the magnetic flux line is computed analytically. The proposed method reduces computational time by nearly five times for the same accuracy with existing procedures, providing cheap and efficient computation. The procedure and some examples to present the usefulness of the proposed method are described
