I remember a post by UC a while ago where he said that it was a common misconception that magnetic brakes worked by the brakes being positively/negatively charged, and the train the other and then they attract and it slows the train down. This is how I thought they worked, so how do magnetic brakes actually work?

If you read through the last part in the article about brakes at Coastersandmore.de then you will know how they work:
http://coastersandmore.de/rides/brake/brake.shtml
(note it's in German so you you might need a translation of the thing before, if you don't know German that is...)

Or you could read the article about "Eddy current brakes" on Wikipedia: http://en.wikipedia.org/wiki/Eddy_current_brake

Loefet and I also ended up talking about it quite a bit in the I305 construction topic (page 69-onward).

http://www.coasterforce.com/forums/view ... &start=952

Start about 2/3 down that page, and it continues (more or less) until the most recent page.

I would really recommend people that are interested in how coasters work to read through the articles that are posted in the "Coaster Basic" section on www.coastersandmore.de . It's really a shame that they haven't been translated into English since they are written in such a way that they are easy to understand but still have all the info you will need to get how the things work, but Google translate (or other) usually gives a satisfactory (at least it's way better than translating from Japanese, etc.) result so that you will be able to read it.

I would also recommended the rest of the articles, especially those posted in the "Ride Insight" section, they have a lot of useful informations and feature a lot of great images...

Thanks for all the links guys they have been really helpful and now I think I understand how they work. I do understand quite a bit of German and had a little read of that article and understood some things in it, so thanks!

Magnetic Brakes cost lots of money but theme parks should save on maintenance .

BTMRR and Ragng Spirit in TDL and TDS got the Magnetic Brakes .

^ Right... That really had not much to do with this topic...

^^ I'm glad that the article helped, as I said before, it's a shame that those articles aren't translated to English since they are really good...
