# Building an electromagnet hover-coaster

Want to know the posibilities of lifting over 300Kgs

How much current will be required of electromagnets holding the coaster carriage lifted above two beams on either side?

Also will it work to place electromagnets on opposing sides (top and bottom, left and right) of the beam to hold the carriage from lifting up or falling down?

You can calculate everything you need using any book or website on electromagnets. This simply isn't something we can simply explain in a forum thread, as it requires a full understanding on how electromagnets work and other electromagnetic principles.

I ran the following through google translate:

"You can calculate everything you need using any book or website on electromagnets. This simply isn't something we can simply explain in a forum thread, as it requires a full understanding on how electromagnets work and other electromagnetic principles."

The translation:

"You need to learn all the answers yourself. You basically need to become a professor of electromagnetism to answer your question and therefore you should quit while you're ahead."

ultravolts, Do not get discouraged just because you haven't received all the information you want to make a hover-coaster. Sarcasm is never useful. Drakkith is exactly correct: You have to study the problem, do research, and find out what others have already done on this subject. Then, when you have doubts or some confusion about processes or mechanisms, come back here to PF and post your question(s). I promise you folks here will try to help you understand the science.

Are you aware that there are already Mag-Lev trains operating in this world? Have you studied how they work? What research has already been done on the subject? Have you found out what engineering problems they had to solve before success? Keep us informed of your progress, I would enjoy a ride on a hover-coaster.
