I did a quick search of this (very long) thread, and couldn't find a reference to MagPeds:

These are like clipless pedals, but use a very strong magnet and a different type of cleat to hold your shoe to the pedal. Here's one review (from a mountain biker):

Here are some more reviews:
Reddit discussion - there are other Reddit discussions, just search. This was from a MTB subreddit, so the review is from the that POV.
https://granfondo-cycling.com/magped-road2-review/ Which contains this - "To release your foot from the pedal, you must simply twist it away from the bike. Doing so requires little force and makes the panicked effort of getting a foot on the ground before you tip over a thing of the past.
This removes the fear that beginners often associate with the use of clipless pedals, and prevents embarrassing situations and bruises."
Confession: I bought a pair of MagPeds a couple of years ago and they are still on the shelf waiting to be fitted. At the moment I use Shimano T8000s, which are flat one side, SPD the other. Generally I find the T8000s excellent - I'm clipped in most of the time, but use the flat side in very busy stop/start traffic, any time I think I would otherwise have to unclip in a hurry.
I bought the Magpeds in order to get off the pedals in a panic moment. I've only had one actual clipless fall, and that was very early on. I didn't actually forget I was clipped in, as such. It was a moment when both I and a driver sort of dithered, I ended up side on to the kerb and went over. The drivers who witnessed it were all actually very concerned, and not one of them laughed (at least not till later maybe).
I think other manufacturers have now gone into the "magnetic clipless" market.
But every so often I have a "only just unclipping in time" moment. Particularly if it's the right foot. I don't know about anybody else, but I'm so used to unclipping the left foot, it's not a problem. But sometimes, at very low speed, or making an awkward manoeuvre, I need to get my right foot out, and I/we just aren't used to doing that. I should practice it, really. I have the clip on the lowest strength setting, and my pedal has never released unintentionally.
And although I'm a fan of dual sided, as in SPD/flat, pedals, I do have to be aware whether I'm clipped in or on the flats. The flat side pins on T8000 are fairly "grippy", so a twist might not actually get your foot off the pedal. I do actually say to myself - "unclipped", a few times, just so I know. And one thing I never do is go half and half. Both feet are either clipped in, or on the flats.
If/when I ever fit my magpeds, I'll leave a review in this thread.
