It's weird to think that in 20 to 30 years well have magnetic fields this strong in every day devices. I wonder how we will deal with issues like this.

- carterschonwald 16y agowhat sort of devices are you thinking about? Pocket fusion reactors and other sorts of plasma bottling tech?

- tocomment 16y agoHow about a portable MRI for starters? You could possibly use it a brain computer interface. You could also perhaps use transcranial magnetic stimulation to send data into your brain? (Just some wild thoughts). On the more mundane side, you could use the diamagnetic effect of high magnetic fields to deflect water from windshields, keep snow off your driveway, give your tires traction on ice. You could even hover over water. I'm sure there are lots of other applications I'm overlooking.

- tocomment 16y agoWhy all the down votes? If these ideas are flawed why not explain it? How are ideas for the application of magnetic fields not in the spirit of hn?
- hugh3 16y agoI think the downvotes are for the unsupported assertion that in 20-30 years we'll have magnets this strong in everyday devices. This seems unlikely, for various reasons.

- cheald 16y agoI don't think that we're ever going to see supermagnets in common consumer devices, just because they can be so ridiculously destructive. The layman tends to think of magnets as fun toys, but the high-end ones are exceptionally dangerous. Walking around with a neodymium magnet in your pocket would get someone killed before the day was out.
- jarin 16y agoOf course! As the trend toward faster processors, more storage, and better battery life in personal electronics begins to reach its limits in the next few decades, a new trend toward destructively powerful superconducting magnets will naturally arise. Take that, Kurzweil!
