SETT OCH ANORDNING FOR TRANSPORT MED MAGNETISKA KRAFTER

摘要

A method and device for magnetically transporting finely divided magnetic particles accumulated or deposited at a space. First a DC magnetic field is exerted to the finely divided magnetic particles so as to magnetize and bring them into an easy-to-be-handled state and then revolving alternating fields are exerted to the magnetized, finely divided magnetic particles, thereby magnetically transporting them.
