00:00Which lifts more, a neodymium magnet or an electromagnet solenoid?
00:04I had this argument with a friend, so I grabbed the 5 best-selling magnet blocks and ran the numbers.
00:10Best deals in the store right now.
00:13Surprise, it isn't close.
00:15This is the big boy, 40x30mm, 3 thick, N35 grade.
00:21Biggest face of any magnet here, so it grips a fridge door or steel cabinet like it's not asking.
00:27And here's the whole answer to the title, no power cord, no coil heating up, no adapter to buy.
00:33It just pulls.
00:35535.
00:37One warning, these snap shut hard.
00:39Keep them away from pacemakers and little fingers.
00:43Now the skinny 130x10, 2mm.
00:47This is my daily driver.
00:502mm thin means you can slide 3 or 4 into a groove and the pull adds up fast,
00:54which is exactly why the big block felt weak to me at first.
00:584.85, so it's the cheapest in the video.
01:01Flat surface, light load, no drama.
01:05This one's different.
01:076mm thick, round, with a hole right through the middle, so it's not just a fridge magnet, it's a mounting
01:13point.
01:14Screw it to a shelf, a wall, a truck bed, anything, and it still pulls.
01:19And because it's a solid 6mm instead of a flat slice, it holds noticeably heavier.
01:25512, 4.6 stars.
01:28This is the one I'd actually build something with.
01:3230mm disc, 3mm thick.
01:35Low profile, slide it under a shelf or a steel plate and it barely sticks out.
01:40Because it's thin, most of its strength sits close to the surface, so stacking 2 is a cheap upgrade over
01:451.
01:465.07.
01:48Thousands already bought it, and it works fine for sensors, jigs, and tool trays.
01:53Same size as the last one, 30x3, but this listing has a 4.9 rating, the highest of anything I
01:59tested, and fewer buyers, which means newer sellers, not worse ones.
02:04You're paying 14 cents more for the same magnet.
02:07Math says take the 4.9.
02:10If price is everything, take the 5.07 version.
02:14Links to all 5 are in the description, plus the part where a solenoid actually wins.

02:22How you can still use a SDR-1.
02:22If this is a SDR-1 where the SDR입니다 is Screen from closing or sliding.
02:22Hopefully, you can use the SDR-1.
02:22Make sure you use the SDR or SDR or SDR-1.
02:23Otherwise, you can use the SDR-1 to upgrade.
