A model is presented for the high-speed uniform rotational reversal of ferrite toroids. This model eliminates the prohibitively high demagnetizing energy usually associated with uniform rotation in toroids. Analysis of the model, to a very good approximation, leads to results identical with those obtained from uniform rotation in isotropic thin films. Experimental confirmation of a high-speed switching mode in ferrite toroids is given.
