train would have moved forward so it will be pushed by that same magnet on the track and pulled by the following electromagnet on the track, which now has the positive voltage across it. So the first would be pushing and the second would be pulling. It takes some time to clearly understand what is going on but it becomes so obvious afterwards. It’s as if the train was "surfing" on waves of voltage.THE MAGSHIP Another interesting application is what is referred to as the magship. This ship has no engine, no propellers and no rudder. It has a unique power source which is electromagnetism. The generator on the boat creates a current which travels from one electrode to another which go underwater on each side of the ship. This makes the water electrically charged. This

only works in salt water because pure water would not conduct the current. The magnets which are located on the bottom of the ship would produce a magnetic field which will push the water away making the ship move forward. There are a lot of problems related with that. The magnetic field could attract metallic objects and even other ships causing many accidents.CONCLUSION As time goes by, transition temperature, critical field (maximum magnetic field intensity that a superconductor can support before failing), current capacity and all other problems are improving slowly. But, at least they show that we are moving in the right direction. A lot of people are getting interested in that field since it promises a lot for the future.
