Door stop

A door stop, comprising:

• a) a block, including:
• a1) a top surface;
• a2) a bottom surface;
• a3) an engaging perimeter substantially orthogonal to each of the top surface and the bottom surface and disposed therebetween, the engaging perimeter including a first engaging surface, a second engaging surface adjacent to the first engaging surface and curved in a concave manner such that it engages with a cylinder of a hinge when in operation, a third engaging surface orthogonal to the first engaging surface and adjacent to the second engaging surface, and a fourth engaging surface adjacent to and orthogonal to the third engaging surface and distal to the second engaging surface;
• and
• a4) a non-engaging perimeter opposite the engaging perimeter and disposed between the top surface and the bottom surface the non-engaging perimeter including a first non-engaging surface that is orthogonal to the fourth engaging surface and substantially parallel to the third engaging surface, thereby forming a protrusion and a second non-engaging surface orthogonal to the first non-engaging surface and adjacent to the first non-engaging surface opposite from the fourth engaging surface;
• and
• b) a plurality of magnets disposed in an array along an exterior of the engaging perimeter.

• b) a plurality of magnets disposed in an array along an exterior of the engaging perimeter;
• and
• c) an engagement layer disposed over the plurality of magnets and configured to have a higher coefficient of friction than an outer surface of the block.
