Tank magnet

So i had this suggested to "trap" any small flakes of rust that may float around in the tank..drop a small magnet down along the inside of the tank and in theory anything metallic would be drawn to it and stick instead of free floating around the tank..seems like it may work. Anyone ver heard of that trick yet???

There is a tank on ebay that has magnets on the bottom.

Old trick dude..
 
i just heard of it.so the magnets are on the inside or the outside of the tank?? guess if its a strong enough one it would attract thru the tanks metal as well
 
I don't see any problem with the magnets, only the probablility that most of the crud that gets into the carbs is not magnetic. :-k

In other words, although they are a good idea, how effective would they really be? :confused:

I place old speaker magnets under the oil pans in some of my cages.
Pull the magnet while draining warm oil to get any metallic bits out and replace magnet when adding new oil.
Far superior to a magnetic drain plug. ;)
Not sure if rust in a tank would be attracted to a magnet though.

True.. i have rinsed a few tanks out that looked good thru the filler hole and from the petcock hole and got lots of chunkies out. had a few screens in there pretty clogged as well with crap.. I had heard of the magnet thing and was wondering if it was worth it or not too.
 
yeah is good old ferric oxide magnetic?
I dont think so.

Are all the bikes equiped with a magnetic oil drain plug?
 
hmmm knew a training sgt. and he told me that when he was on the rifle range teaching reservists he would order the boys back to the trucks to get the brass magnet to pick up the spent cartridges.

the guy likely stole it form a movie but he said some of them actually didnt know.

You might want to explain that thought to all of the manufacturers of audio and video tapes. They were nothing more than a polyester base or PET that was coated with iron oxide and sealed. The record and erase heads simply realigned the magnetic domains produced by the iron oxide particles to contain readable signals that could be converted to sound, images or both.
You missed this one.

Yes Joe Sony and his sprinkling of iron filings to a silk ribbon post WWII is an inspiration to us all.

I do not think Red rust is attracted to a magnet. I could of course be wrong but I have tried to pick up red rust with a magnet and never could.

You misunderstood this one maybe?

OK.

Rust, or Fe2O3, has a very weak response to magnetism. Not enough to have a magnet pick it up in your gas tank. Iron Oxide is used on tape in part because of it's weak response to magnetism.
 
I would think that while Iron Oxide is not magnetic, rust is rarely just iron oxide! It has flakes of unoxidized iron mixed in.

Anyhow, I think Ill slap an old harddrive magnet on the bottom of my tank in a spot that is visible and check it later to see if its caught anything. Cant hurt, I like the idea.

yes good gollly those hard drive magnets are amazing for the size of them.
fragile but powerful.
 
When I was cleaning my carbs there was a reddish-brown clay-like residue in the bowls. It was attracted by a magnet but it seemed like the attraction was a little weak. I was trying to confirm it was rust.
