Scrap Metal Test Magnet 18 lb Rare Earth Neodymium N52 Check Gold Silver KM04

Description

Metal Testing Magnet For Recycling Industrial Metals And Testing Gold, Silver, Etc.
We have mounted a powerful 1/2" diameter x 1/2" tall cylinder N52 grade neodymium-iron-boron magnet in an aluminum case for industrial and hobby use. It comes with an extra heavy duty split ring for attaching a hook, rope, wire, or fishing line. Here are some possible uses:
Identify and sort steel grades and metal alloys that contain iron, nickel, or cobalt (limitations exist).
Identify/sort chrome plated steel items from polished aluminum, silver, and non-magnetic grades of stainless steel.
Identify/sort solid brass and bronze from plated steel items (handy in the antique market and hardware store).
Identify/sort some types of costume (fake) jewelry, which often use steel or nickel as the base material under the plating. Please be aware, many nickel alloys including cupronickel (modern US 5 cent coins), German Silver, Nickel Silver, will not react to the magnet, despite containing nickel.  It has to do with the crystal structure of the metal, and is the same reason that some stainless steels are non-magnetic, even though they contain two ferromagnetic elements.
Use as a very powerful magnetic pickup, not like those 1/2 pound jokes at the hardware store.
Attach to your fishing line and cast away.  You will find all sorts of sunken goodies.  I am told that if you live in a big city, bridges are an excellent place to go "magnet fishing."  If you want to retrieve really big items (like engine blocks), use this magnet as an underwater finder, when it latches on to something, you can drop a very large normal magnet and pull up as much as you or your boat winch will lift.
Also handy for science experiments involving ferromagnetism.
The magnet insert is rated at 18 lbs (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). Take a look at the pictures, it holds a 13 lb sledge hammer with rough and rounded edges in mid air with no problems. A vinyl cap is included to buffer the strength of the magnet and protect the head when it is not in use.
Dimensions are:
3/4" (19mm)diameter x 7/8" (22mm) tall head
2" (50mm)overall length
3/8" (10mm) diameter handle
1/2" (13mm) diameter heavy-duty stainless steel split ring.
