Hi there, I got question here, is it possible to build a rocket by using magnetism concept? The rocket doesn't have to fly very high up, that means can fly inside a hall is more than enough. Please help me with any ideas that anyone have in mind. I have thought of a coil gun might be similarly to the concept of it. I would like anyone whom might be helpful enough to give me information more on the coil gun and how to construct it.Thank you.
