How do magnetic launch coasters work? | LSMs & LIMs explained

Over the past few years launch coasters have been popping up everywhere. Rides like VelociCoaster, Hagrid's Magical Creature Motorbike Adventure, Guardians of the Galaxy: Cosmic Rewind, and Tron, are all magnetic launch coasters - as are many other rides around the world. But, how do they work, and why are they so popular, and will we see more in the future?

Wake up, new Coaster Bot video just dropped

[MadMovieMakers]

If peopke ever think old stuff is always better, just remind them that the LIM system on Superman The Escape took months to get working properly, compared to the reliable launch coasters of today

Best explanation of this I've seen. Never realized the magnetic field itself had motion.

[CatsnCoasters]

LSM launches certainly seem to be the future and I'm all for it...however, you cant beat the intensity of a hydraulic launch. Coasterbot - quickly becoming the encyclopedia for all things theme park related. Superb content. 👍

Parks also like how they usually have a smaller footprint since you don’t have to have a massive lift hill to get to quite a high speed, the lack of a lift hill being particularly attractive to parks like Phantasialand who have issues with height restrictions.

Great video!

Very good video. Certainly did your research and explained it extremely well. Great editing to suit the audio too.👌🏼👏🏻

[The_Tedstar]

I'm using all your videos to teach my mum about rollercoasters!

[RollerbazAndCoasterDad]

Hooray for this Coasterbot video on the best noise in Theme Parks. I love a hydraulic launch, I know it's harder and more forceful but that NOISE of a magnetic launch is amazing.

that feeling when coaster bot puts your home coaster footage in his videos

RIP Wicked Twister...one hell of a fun ride. Had many good times on that

LIMs & LSMs are both popular magnetic systems used for roller coasters when the train launches! Some coasters used this when the train hits the brakes when the ride ends! Great video Coaster Bot! You help us learn about roller coasters more than ever! Please keep it up! 👍👍👍

I love the explained series, you have taught me much of what I now know about rollercoasters! Thanks for this series :)

[chazgames]

On lsm launch coasters and velocicoaster especially, you can really feel the train almost being held back against the tension caused by the magnetic field, when it reaches the holding section

[vortexluigirosalina]

Glad most parks are using LSMs now a days

[Fluster]

Thanks, always wanted to know more about these magnetic launches, awesome video and explanation. Please keep making more of these explained videos, I love them.

[drewking_]

I craved a new "explained" video for months. So glad you posted one

[chadmichael_]

I like the sound of the magnet launches.

[pizzapuntthomas]

Thank you for this video! I've been watching you other video about launches, but I couldn't really understand the difference. This video helped me a lot!

[spacepowerofficial]

I literally looked up that topic 2 days ago, thank you :)

[caleb.butlin]

You know it’s a good day when coaster bot gives you a brand new video!
