Neodymium Metal/Gold/Silver Testing Magnet Key Chain. 

Very small and very powerful.  Neodymium magnets (the strongest kind available), can be difficult to handle and fragile, not so good for constant handling and use. Not to mention, they are so small they are easily misplaced or lost.  However, they are the best type of magnet for detecting iron content due to their superior field strength.

We have mounted a powerful 3/8" diameter x 3/8" diameter cylinder N52 grade neodymium-iron-boron magnet in brass for industrial and hobby use. It comes with a split ring for easy carrying, and comes with a protective vinyl cap.

  • Identify and sort steel grades and metal alloys that contain iron, nickel, or cobalt.
  • Identify/sort chrome plated 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 uses steel or nickel as the base material under the plating.
  • 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

10 lbs Pull Force Rated Magnet Insert

The magnet insert is rated at 10 lbs pull force (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). Pull force is not necessarily lifting strength, which depends on many factors. Take a look at the last picture, it's holding a sledge hammer in mid air with no problems.

Dimensions are:

1/2" (12.5mm) diameter x 3/4" (19mm) tall head

1-3/4" (45mm) overall length

3/8" (9.5mm)diameter handle

1/2" (12.5mm) diameter stainless steel split ring.

The brass casing protects the magnet from chipping and breaking, and makes removing iron and steel shavings much easier. We also include a protective vinyl cap for when the magnet is not in use. These are made in the USA.
