Abstract
Demagnetizing factors of the rectangular rod and cylinder magnetized uniformly along the long axis are found to be expressed by the simple and approximate expressions 1/(2n+1) and 1/[2(2n/(π)1/2) +1], respectively, where n is the dimensional ratio. The error which is the difference of the value evaluated by 1/(2n+1) from the value evaluated by the exact expression of the demagnetizing factor is less than 5.48% for the rectangular rod with nn/(π)1/2) +1] for the cylinder is also found to be less than 4.25% for n<100.This publication has 4 references indexed in Scilit:
