My work is a “perpetual motion machine”. The reason why I choose to make this is that I want to know whether the perpetual motion machine can really be made. I choose to use magnetic force to promote the operation of the stick, so as to convert it into electric energy then to light the bulb. Although the service life of the magnet is only 400 years, strictly speaking, it does not belong to the perpetual motion machine, but it is already a perpetual motion machine for our students. My original intention of this project is to hope that we can use magnetic force or other items to generate electricity instead of coal and natural gas, so as to greatly reduce the damage to the environment. However, there is no perpetual motion machine in the nowadays world , and the teaching videos and those “professional essay” on the Internet are also fake. I tried various methods — putting the position of the magnet again, changing the direction of the magnet, trying to solve the problem that the magnet is magnetized, and increasing the number of magnets, but these are useless because the perpetual motion machine violates the law of conservation of energy, Perpetual motion machine refers to a machine that can move continuously and do external work without inputting any heat source and energy from the outside, and a machine that can do external work forever without consuming energy. Obviously, this is impossible now.
