Strong magnets can affect blood
Thursday June 3, 2004
Although blood does not appear to be magnetic at common levels of magnetism, I believe you are wrong to say it is not affected by magnetism at all (Bad Science, May 27). With a sufficient magnetic field it is possible to levitate any material, including blood, or even an entire frog using magnetism.
As to the medical benefits of using magnetism in this way, apparently the frog suffered no ill effects.
