A method of making a flexible magnetized sheet is provided. The method may comprise the steps of (1) using cold extrusion to produce a highly viscous fluid magnetizable sheet, (2) passing the sheet through a magnetic field to create an uncured magnetized sheet, and (3) curing the sheet with electron beam curing. The fluid mixture may comprise magnetizable particles with a random charge orientation and an acrylic resin. The components of the mixture are cool when passed through an extrusion die. The extruded fluid sheet allows for the sheet to be magnetized and then, instead of curing by cooling, cured by the bombardment of electrons via an electron beam (EB) generator. The method can eliminate the heat of extrusion and can allow for more freedom of orientation because the sheet does not cure until it reaches the electron beam curing station.
