The lower the L/D Ratio (Length to Diameter), greater is the Coercive Force required to demagnetise the item. But shape is not the only factor. You also have to take into account such properties as heat treatment and alloying. Cheerio's Michel ----------- Start Original Message ----------- : is the coercive force depend on the shape ? Provided two samples are made of the same material but different shape, you measure their coercive force could you end up with different results ? ------------ End Original Message ------------ Follow Ups: Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : In one word, YES!
