Abstract: Claims of “Free Energy” generation using Perpetual Motion Machines (PMM) are usually discounted by the scientific community since PMMs are considered impossible, as a direct corollary of the Law of Conservation of Energy. However for the scientifically inquisitive mind, the urge to distill reasons which make some systems appear as PMMs, remains a factor. Recently a system on permanent magnets has been observed by the author, whose designer claimed that his system can provide ‘free energy’. i.e., the output of the system is greater than the input. This system comprises of eight magnets arranged at equal distances at the rim of a circular disk and a ring magnet at the centre of the disk as shown in Fig. 1. The first magnet at the rim of the circular disk has its north aligned with axis of rotation and facing towards it. The next magnet placed after 1/8th of the circumference is rotated by an angle of 450 around z-axis such that after traveling half circumference the magnet rotates through 1800 as shown in Fig 2. The input is ring magnet which has an inner radius of 31.75 mm and an outer radius of 50.8 mm as shown in Fig. 3. The ring magnet is positioned at an angle between 300- 400, from the horizontal upper surface of the disk. The lower face of the ring magnet is North Pole and the upper face acts as South Pole or vice versa. In either case the face of the bar magnet facing the ring magnet is such that there is a repulsive force between the two. As the disk rotates initially, the ring magnet is positioned manually by rotating it around it’s z-axis at an angle of 300-400 to an axis parallel to the upper surface of the disk such that at an instant there exists a repulsive force between a pair of bar magnets (separated by 1/2th of the circumference) and the ring magnet. The system has been analyzed using theoretical calculations and simulation with PRO ENGINEER Wildfire 5.0 which shows that it is not a free energy system.
