Magnetic alphanumeric characters having substantially the capability to be properly aligned to one another during display is proposed. The characters consist of magnetic materials with concentrated magnetic strength on one face.

The zig-zag edges allow more than one alphanumeric character to be installed in a straight line vertically, horizontally and at an angle.
