Abstract
A magnetic sheet includes a first sheet, a second sheet, and a number of microcapsules disposed between the first and the second sheets. Each microcapsule contains magnetic particles, clustered magnetic particles, non-magnetic particles, clustered non-magnetic particles, a suspending agent, and a solvent. The magnetic sheet is designed so that the magnetic particles reacting to a rotating magnetic line of force applied from a side of the first sheet rotate and move in a direction opposite to a direction of rotation of the magnetic line of force and aggregate near a center of the microcapsule to stay stationary.
