Iron Filings
Yes, we have this hard to find accessory for magnet studies. Dramatically illustrate the magnetic lines of force surrounding magnets. Hint: To assist with clean up, place either the filings or the magnet inside a plastic bag and seal it before exposing the magnet to the iron filings. Oh...too late you say? Your magnets are already covered with iron filings? Try to pinch off as much as you can, then use really sticky tape to remove the rest. This problem can also be avoided by getting the filings in a sealed case. We just so happen to sell these (see below).
CHEM.04    Iron, metal filings, approx. 35 g (about a tablespoonful)    $2.00/vial
MGNT.45    Iron filings in clear sealed case    $4.95 each
MGNT.46    Filings & pink sand in sealed case    $4.95 each

Magnetic Field Viewing Card
Amazing viewer card allows you to see exactly how magnetic poles are arranged on any magnet. Credit card size viewer works like iron filings, only it defines magnetic poles more precisely. Dark areas represent poles, light lines show where fields cancel.
MGNT.44    $4.95 each

Lodestone
The original magnet! Naturally-occurring iron-rich rock that is actually magnetic! Will pick up paper clips, gather iron filings & deflect compass needles. Individual pieces approximately 2 to 3 cm across.
ROCK.04    $1.00 each

Small Ceramic Magnet, disk shape
Disks are 3/4" diameter, 3/16" thick & slightly stronger than small ring magnets below. Glue just about any small object (natural or kid-made) to one side of these disks to make your own refrigerator magnets. These are fairly strong for their size. Magnetized through their thickness, with single poles on opposite faces.
MGNT.01    $0.30 each

Small Ceramic Magnet, ring shape
Round ceramic ring magnets for use in school, home, office or shop. Demonstrate attractive & repellent magnetic forces. Rings are 1/4" thick and have a 1/4" dia. hole. (Not big enough for a pencil, but will easily slip over a straw or bamboo skewer to demonstrate repulsion. See below for larger rings.) Overall diameter 3/4 inch. Magnetized through their thickness, with single poles on opposite faces.
MGNT.04    $0.30 each

Large Ceramic Ring Magnet
Powerful round ceramic ring magnet. 1.25" diameter, 3/16" thick with hole big enough (3/8") to do the "levitating magnet" demonstration (like poles repel) by slipping 2 of them over a pencil. Magnetized through their thickness, with single poles on opposite faces. These magnets are strong enough so that a pair can easily pinch skin between them if caution is not used. (Believe me, I know.) They can also be fairly brittle and may break if allowed to slap together unhindered.
MGNT.40    $1.00 each

Ceramic Magnet, medium rectangular block
Excellent for making working models of electric motors. Blocks are 3/16" thick by 1" long by 3/4" wide with a 3/16" diameter hole. Magnetized through their thickness, with N/S poles on the faces.
MGNT.06    $0.50 each

Adults: Place one MGNT.13 in your open palm, place another against the underside of the same hand, and you can hold your hand vertically without the magnets falling off! Surplus items, many have imperfect paint jobs, rust spots or chips. WARNING: These magnets can easily pinch skin if caution is not used. Definitely NOT for young children. Ages 12+ only.

Cow Magnets
No, these magnets do not attract cows! They are powerful bar magnets that are placed down a cow's throat to reside in it's first stomach for the life of the cow. Why? Well, cows tend to be indiscriminate eaters, and will swallow all sorts of foreign objects like staples, bits of wire, nails, screws, etc. during chow time in the field. This "tramp iron" (as it is called) could be deadly to our bovine friend if it reached the cow's intestine and pierced it. A "magnet in residence" keeps the iron from getting that far. Three inches long, can be used like any other magnet in the classroom, magnetized along length.
MGNT.18    Solid, smooth metallic cylinder with rounded ends    $9.95 each

Moo Magnet Kit
Cow magnet activity kit, contains one "dissectable" cow magnet (can be taken apart into 5 thick ring magnets and the associated hardware that holds them together), plus a 16 page activity book that tells the history and uses of magnetism, gives experiments you can do with your Moo Magnet (or other magnets), and important basic facts of magnets and magnetism. Dissectable cow magnet for experiments only, not intended for use in a cow! Ages 6 and up.
MGNT.42    $11.95/kit

Remagnetizer
For revitalizing old Alnico, steel bars and horseshoe magnets. Save your science department time and money every school year. Instead of throwing away expensive Alnico, horseshoe and bar magnets that have lost their magnetism due to improper storage and repelling experiments, remagnetize them as often as you need with The Remagnetizer. (Other modern magnet materials such as ceramic, neodymium & samarium cobalt do not need remagnetizing.) Simply "recharge" your magnets by matching up opposite poles with The Remagnetizer (N to S and S to N). When the poles attract, the superior magnetism from the large neodymium magnets within The Remagnetizer rejuvenates the weak Alnico magnets. Adult supervision recommended.
MGNT.39    $75.00 each

(See Rentals section for info on short-term rentals.)
