The U-shape, the horse-shoe shape is not magnet.
All pieces are stainless steel or ferrous, ferromagnetic.
It becomes electromagnet only due to the coils in the moment when we apply the voltage from battery.
Then the whole core become very strong magnetized.
How is it possible to maintain that magnetization for long time after the battery is removed?
...as a transformer; it demonstrates how permanent magnets are made, and is a holder of perpetual motion. The latter will be demonstrated now because it is important for you to see it defy some of the most basic laws of physics and a few, more sophisticated laws of modern EM theory.
There are many ways to learn to code these days. From coding bootcamps like Flatiron School to online courses to totally free beginner resources. The best way to learn to code depends on many factors, but the most important one is you. See what course is best for you.
Why do you say the conservation energy does not apply here?
Here is a good tip to the rocket people. Make the rocket's head strong North Pole magnet, and the tail end strong South Pole magnet, and then shut to on the moon's North end, then you will have better success.
