Magnet is a material or object that produce magnetic fields. This magnetic field is invisible but is responsible for the most notable property of a magnet : a force that pulls on other ferromagnetic material, such as iron, steel, nickel, cobalt, etc. and attract or repels other magnets. Due to its ability, the magnetic power is a technology that is still being developed in the future to be applied to trains. Magnetic technology will be a solution to solve these problems: speed, cost savings, and not causing damage to the environment in the future. This may be why people research about how to develop technology in trains, so that they can make transportation business easier, not damaging to the environment, and also very fast.
