I used an after market magnetic oil drain plug and after the third oil change it broke in half and was left inside the drain pan. I had to drill it out and reuse the oem drain plug back! Please beware!

Avoid using Magnetic Oil Drain Plug

Agree. They make magnetic drain plugs out of steel. My Porsche has a factory magnetic drain plug that has never broken in 50+ years. https://www.ecstuning.com/b-genuine-porsche-parts/oil-drain-plug/99906300802/

I dunno if I'd want a buildup of captured material in my filter...it'd be good to remove it every time the filter was changed, but you already have the drain bolt out when doing a change and can clean that. Keeping debris in the filter puts it directly in the path of oil flow vs letting it settle and stay at the bottom of the pan, and you'd have no way to see how much buildup you had. Suddenly accumulating a lot could be a sign to get it checked out but you'd never know.Yikes! They sell magnets that wrap around your oil filter. If I can find the right sized refrigerator magnet, then I might slap it on mine next time lol
Don't buy any of the pathetic aluminum or anodized aluminum plugs. Your OE plug was not aluminum.
Here are some, that I've used, and no specific order, that won't give you any heartache.

Corvettte guys run em cuz of proven side by side split filter comparisons and because the filter mags have much larger surface area than the plugs so they trap way more than the plugs. There's a decades long debate over whether the magnetic plugs are too low on pans to even do anything when oil is flowing. However, one downside I've seen from the LS guys is that if you're sending it too hard on a track day, then there's been anecdotal stories of the magnet coming off, which can easily be fixed with a hose clamp. Some have stated this is the result of using a counterfeit Filtermag because these people state that a Filtermag is impossible to take off without prying with a screwdriver (imo, this is not the same as the G forces you experience on a track day, say for example when you fly off the tarmac). Personally, I don't even bother with magnets because many Toyotas have literally made it to a million miles without magnets.

This might be the missing piece in my logic then, I was picturing a magnet not much bigger than the drain plug and thinking how all the debris would be held in a way that left it susceptible to re-entering the oil stream. If it's spread out that would be much less of a concern. And since all working oil goes through the filter but not necessarily the bottom of the case...maybe they deserve more credit than I'm giving them.
Oil is in a continual loop. It doesn't all go thru the filter. So, it all doesn't need to move by the magnet. The drainplug magnet will catch plenty as there is plenty of oil movement around the inside of the pan.
A Filtermag will catch plenty too. Anything, that either catches, frees up filter media space.
Anything it catches that is smaller than the filter rating is a plus too.
Anything caught by my magnetic drainplug doesn't grind thru the oil pump.
My Filtermags slide on/off easily. They even pull off easily. I've never needed a screwdriver to 'pry' one off. And, they are commonly stolen while at the tire shop, dealership, or inspection station. In the past 4 years, I've lost 2 quality magnetic drainplugs to 2 different dealerships.... they were simply replaced by the tech for no reason other than they hope that they wouldn't get caught. One was an ol' car that got a complementary change and other part of 2 year new car free maintenance.
Toyota also uses magnets on their diffs/xcases and transmissions too. Seems to work there passively there just fine.
Once its caught by the magnet, it doesn't go anywhere until you clean it off.
I could care less what the Corvette or any other guys do. I have magnetic drainplugs on all my cars. They simply work.
Logic? don't need to figure out why it works or doesn't. Simply DIY your own maintenance and see what it picks up every time, on either the inside of filter shell using a filtermag, or on the drainplug magnet.
Since I already posted the common competitors concerning drain plugs, a filter magnet is an easy DIY for "canister" filters. So glad that the new Rav4 has a screw-on can. I hate the cartridge on my 2gr Highlanderavalons.
You can recycle ol' harddrive, construction, or speaker magnets, so don't need to bother buying the below, but listed for research.

Sure, but the decades long debate goes: there's no proof the stuff the plug magnet picks up wouldn't be picked up by your oil filter or dumped out during your next oil change
Dude I've I always wondered why they had those diff and transfer case plugs magnetized but not the oil drain plug, probably because no filter in the diff or transfer cases
There is no debate. Filter has a 30-50micron rating. Magnet doesn't have a micron limitation.
The magnet is a filter. It always has been. Whether you need it or not is for you to decide. All my engine drainplugs have been upgraded to a magnetic drainplug. My vehicles aren't disposable like so many members.
Even more amusing is the 'hit and run' thread starter.

Just pointing out opposing theories on this long-running debate that'll continue until the end of time so forum members can come to an informed and wise consumer decision. If you read my posts from earlier, I'm more than open to the idea of a refrigerator magnet lol or if someone donates a Filtermag to me for scientific purposes then i'll be more than happy to run it lol but in the meantime, a neodyne magnet isn't worth $70 and Matt Farah's LS400 crossed 1 million miles with the stock non-magnetized drain plug.
