Permanent Magnets are known from thousands of years and this human eagerness to utilize magnetic force for useful work. Magnets have north and south poles, similar pole always repel and opposite poles attract to each other. Magnetic Strips are made of thousands of tiny magnets in similar arrangement in the form of long strip. In this article magnetic force behavior of magnetic strips over water surface in two different cases has been discussed. A linear acceleration is generated along the magnetic strip which is responsible for the motion of movable disk in both directions only by changing the inclination angle, and in second case the continuous force on the internal disk which makes the disk rotating over the water surface. Experimental result is explained by using mathematical modelling.
