Abstract

A magnetic roller may comprise a magnetized outer surface and an internal chamber. A temperature control system may be in communication with the internal chamber, and a fluid capable of heat transfer may circulate within the internal chamber and the temperature control system. The magnetic roller may be used to produce magnetic sheets having magnetizable particles that are aligned according the a magnetic field generated by the magnetic roller. The magnetic sheet may be provided in a pliable form wherein magnetizable particles may shift orientation when exposed to the magnetic field. Heat may be transferred between the sheet and the magnetic roller to cause solidification of the magnetic material and prevent dealignment of the magnetic particles.
