Build Your Own Magnetic Sweeper

- Magnetic sweepers can help keep your parking lot clear of nails and screws that cause flat tires. At SuperMagnetMan we also have this problem so we made our own magnetic sweeper to pick up metal debris in our parking lot and hopefully reduce the number of flat tires. This video will show the difference between ceramic and neodymium magnets in magnetic sweepers and hopefully you can build your own as well. Thanks again for watching and we would LOVE for you to share this video:)

Good idea. Every parking lot should have one as part of their maintenance.
Wrap the pipe in a layer or two of SaranWrap before using.
When you’re ready to clean, slit the SaranWrap on the top of the tube, pull off and throw away.
Hey, Cool man, I mean Super Magnet Man! You may want to move the rope down to the bolts. This way is less likely with swing (raise) the magnet when you pull the rope. Improvements are indeed endless in possibility. Cool man. great job on the the presentation.
I live out in rural Minnesota on an old farm, with tons of nails, wire, old cans, etc. in the yard; we also have an old barn that loses shingles whenever a good wind comes up - and nails come with them sometimes. The hardware store magnetic sweeper I got to help deal with this is pretty weak. Thinking about mounting some magnets in front of lawn more tires, and under my kids' wagon so that wherever I go in either one, we're gradually cleaning up the driveway and yard. Thanks!
We have a little wheeled cart that holds a 12 volt battery.
There is a switch on the handle that we flip
to enable the electromagnet inside the PVC.
After walking around the area picking up stuff,
we pull the assembly over to the corner, where
we switch it off, and all the metals falls off for
easy cleanup.
My neighbor, who lives on a sandy road with lots of nails,
extended the idea and added something similar to
his car bumper. He flips a switch inside the car
to collect metal while driving, then when he gets
on the paved road, he turns it off and dumps
it on his other neighbors road.
Funny guy, old Ralph.
THanks for THinking !
Interesting:) It would take something to keep the electromagnet cool. Generally a 12 volt battery would get very hot in 30 seconds and probably hot enough to melt through PVC. But you are right that the electromagnet makes it convenient to cut on and off. I have made one that a guy attached to the PTO on his tractor and had a trap door design on the bottom. As the door opened the metal fell off. Then he would close it and go back to searching for metal. So the same thing can be done with permanent magnets.
@@SuperMagnetMan Would be kinda cool to use a strong electromagnet diametrically opposed to the permanent magnet, which you could briefly pulse for a couple of seconds just to release the harvested metals. You would have to be very precise with the current though, otherwise you'd just pull the stuff right back to the surface. It would have to be just enough to cancel out the permanent magnets. The advantage would be that it would only be activated for a few seconds, so it wouldn't be as likely to overheat.
Can't wait to make one to clean up the bike Lanes for e-bikes. I have a pet carrier that goes will act like a trailer and I would like to make like four of those PVC things and mount it underneath the pet carrier and just drive down the bike lanes and clean up because it's terrible flats like crazy
Loved the show. Very ingenious.
Welcome back.
You forgot to add a material releaser. Or it is a real pain to get off. What is the realistic distance to be able to "release" that material? And then you have to have the force to be able to pull the material off or drop ot off all at once. Maybe using the swivel magnet tecnique using a lever (used on other high capacity magnet pickup tools) to cancel the manetic field for release. You need puncture proof tires so metal pieces don't cause flats! I work at a metal fab company. Picking it up can be easy but getting it off "from a neo mag" has to have a minimum distance or it won't come off timely or effectively. That is why others use ceramic. The density of the flux creates such a pull that you have to find a minimum distance that you can pull off the material or have a mechanism that can withstand the force needed to easily release the material quickly.
Nice… was looking for inspiration. Have a lawnmower axle spare and a bunch of microwave magnetron magnets: the PVC pipe was something I hadn’t thought of!
I wish you showed how to adjust wheel height
This would also be very handy to find meteorites. Right now I'm using a 60mm × 30mm neodymium that produces 250 lbs of pull. It does okay, but doesn't cover a large erea.
Awe I was trying to come up with an invention idea for my 7 year old and spice we treating down buildings at my mother in laws house I searched how to magnetize a rake. Since it already exists well my question is how would you make a "kill switch" on it?
What would happen if I wrapped a high voltage coil around a Halbach array?
Could a small magnet (1" X 1" X .5") with a 0.5" hole in it be used to hold a small bearing to center a drill bit on an engine block.? If so, is there a supplier of custom made magnets? Enjoy your videos - Thanks!
Now just add a small conveyor to drop the contents in a container on top. Ether fabric, step, or cup. And can you list where you got the side adjusting brackets, foam pieces, large bolts, wood anchor patterns in the description? Thanks ahead. And thanks for the demo. I'm trying to make an all in one pickup to use at my steel fab workplace. I generally have to sweep it up but don't get it all or in the cracks. So I want it to pick it up and dump it in a container as I go! And then when it is full 10 to 20bl be able to just empty the container.
John - thanks for the suggestion - I will put it in there but I just laser cut the side brackets but everything else was from home Depot. One suggestion for your application is to add to this a brush that can dislodge things and then the magnet can pick it up. We designed a large one for a guy making these for large metal recycling places and he was making a road sweeper and just added the magnet array to pick up the debris after the brush dislodged it. He said it worked great and No more flat tires!!!:)
Where can i get that brackets 😢
👏👏👏👏👏
Your site does not have these magnets for sale there. Where can we get them?

This is the magnets that I used:)
@@SuperMagnetMan oh! Only $60 per magnet!! So it’s a $240 magnetic sweep!! I’m in the process of building one of these, but I’d much sooner make an electromagnet powered by some 15 year lithium cells for about 90% less (considering the copper coil is made with scraps or even salvaged transformers and the same can be said about lithium cells)…
This also has the benefit of being able to flip a switch and just DUMP the swept metal instead of having to fight it off…
In fact, now that I’m picturing the “scraping” - that may be the biggest flaw in your whole design. Metal shards can slice a person to the bone…. The NEO magnets are probably TOO STRONG for this application because look how hard you had to struggle JUST TO SLIDE ONE CUBE OFF THE PLEXIGLASS!!!
To IMPROVE your design, you need to make an INTERNAL CYLINDER that can be easily removed so the swept up materials simply drop from the PVC…
Since you chose to use those overkill tires, I’d also recommend an “OPEN TOP” outer shell so that the “INNER CYLINDER” (holding the magnets) can just be LIFTED OUT with a separate pull tab of some kind.
Lastly, the rope idea is silly. I’m glad you suggested swapping it for a proper handle so this can be pulled or pushed instead of walked like a teacup Pomeranian.
I’m not the magnet expert - but is there a way to ENHANCE the power of magnets the way an electromagnet can be? Meaning, regardless of the magnet type, can a current be sent thru it to make it stronger?? Hence opening the door to CHEAPER magnets, greater coverage area, and an more overall practical tool??
All I know about altering a magnet’s power is by HEATING it.. Which drains the magnet. Maybe running a current thru it actually reduces power since heat will be generated…
But Ive never explored this!!! you?
Certainly interesting yo say the least.
Nail ..
