Magnets seem to be creeping into mountain biking at the moment. There are two pedal brands (that we know of) using them for a
halfway house between clips and flats;
bottle holders that use magnets for a quicker release and even a
Canyon concept bike making use of magnets for suspension.
The latest to throw their hat into this ring is the brand MagSuck. Since the advent of narrow wide chainrings, dropping chains are certainly less common these days however, for those that are still having issues or still begrudgingly use a chainguide, this could be an attractive solution.
Based out of China, MagSuck produce a chainring that uses small magnets between each tooth to keep the chain firmly in place. MagSuck goes so far as to make the claim it will fully eliminate chain drops. The brand also claims that there is reduced chain noise when using the ring as the chain shakes around less and finally that there shouldn't be any loss of power as you crank the pedals.
MagSuck details
Material 7075 T6 aluminum
Options RaceFace Cinch, SRAM GXP, M8000, 104BCD
Weight 67-70 grams
Price USD $69.50-$89.50
The MagSuck ring has a claimed weight of 67 grams for a 32 tooth ring, which is about on par with a more conventional chainring thanks to the holes drilled into the ring to insert the magnets. Plus if it means you can ditch a chain guide, then you're cutting that weight as well.
MagSuck sell the chainring worldwide for USD $69.50-$89.50 depending on what model. They also sell a full crankset if someone wants to do more of an overhaul on their drivetrain.

Rocky and rooty trails that shake out your tooth fillings, still drop chains, even with narrow/wide.
Also, having magnets sucking at your chain during pedaling would decrease efficiency?
They also have the widest choice on the market, anodizing colors, cranksets interfaces, boost, Al or Ti, can't go wrong with them
There really is no easy explanation of this phenomena as it is usually taught towards the end of quantuum mechanics course
It certainly does suck Garth.
We've had magnets down for about a hundred years.
*** when used in conjunction with clutch derailleur proper tensioned brand new chain and sprocket"
that has the fine print "when used in conjunction with proper diet"

I dunno, if I was trying to sell a product I think I'd use more than Google translate than be inspired by my surrounds.
Haven't had a chainsuck since the days of tripple chainrings, seems about time to start having them again.
(Damn it! Now I got "Let it go" stuck on my brain. Stupid magnet-brain)
I thought about (as a joke)
- magnet'ed brake levelers/gloves (you will never miss you brake by thingers)
- magnet'ed seatpost-tubes (your mechanic will always insert seatpost as need as you need)
Alsow it can be "next word" for tubeless seals - add some metall shavings into seal and,
if you are punctured your tyre, just attach the magnet to a hole
and so on : )
*as deep as you need
What's next? Once you've got enough metal implants in your body, you can just take a dive into your wardrobe and your magnetic body armour will pop into place. Not sure whether titanium is being attracted by magnets though, have to find out. If you're getting steel implants, chances are it will be austenitic stainless steel which won't be attracted by magnets. Not sure what they're using though, 316L grade surgical steel? I'm an armchair surgeon solely educated by Carcass tunes so I might be slightly off.
I wonder if this could aid with backpedal chain retention
At the big end of the cassette. E.thirteen already makes the climbing cogs replaceable on theirs, but it doesn't retain well (backwards) in my experience.
Add magntets FTW?
Nope still can’t see a problem unless you’re trying to outrun a T-1000 Terminator.
Magsuck.... **Not suitable for mud riding**
Like I need any more pedalling resistance or dirt to stick to my chainring.....
