主权项

1. A method for repelling an elasmobranch comprising: placing a permanent high-pull-force magnet that generates a magnetic field sufficient to repel an elasmobranch into the environment of the elasmobranch wherein the high-pull-force magnet comprises the following properties:
(i) a pull force of greater than about 50 pounds; (ii) a nominal strength of greater than about 5000 gauss alone or in combination with one or more other magnets; (iii) a greater than about 5 gauss of magnetic strength at a distance of about 0.01 m to about 1.0 m; andwherein said permanent high-pull-force magnet is attached to a human body or to clothing or an accessory associated with a human body.
