Our best seller! Excellent magnet for science investigations or just plain play, suitable for nursery school to nursing home. Strong 5 cm long block magnet encased in brightly coloured plastic, with 11 cm handle.
MGNT.02 Assorted colours $2.95 each
Magnetic Counting Chips
Well, the chips themselves are not magnets, but they are attracted to magnets due to the ring of ferrous metal around each lightweight transparent plastic disk. Can be used as math manipulatives, their mixed colours look great projected on an overhead screen.
MGNT.03 Bag of 100, 2 cm dia. $3.95/bag
Colourful magnetic marbles for creative learning, magic & discovery! Permanent magnetic strength, recommended for ages 6 & up. Come in 10 different colours, ¾ inch diameter.
MGNT.05 $0.30 each
As your students make compass needles dance back and forth under their magnet's influence, they experience the feeling of PHENOMENAL COSMIC POWER AND ULTIMATE CONTROL!!! OK, maybe I got carried away, but it IS fun. Pocket compasses, air filled. COMP.11 is the most popular with those teaching magnetism. COMP.08 is about the size of the wee little compasses that you used to get as prizes in Cracker Jack boxes. COMP.07 has no NSEW markings at all, but because it is clear glass top and bottom, they look great surrounding a small bar magnet on an overhead projector. At this price, don't expect to find your way out of the woods with these; they are intended as N/S indicators to show the effect of magnets on compasses.
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) $2.95/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 Kit
This kit allows you to see how magnetic poles are arranged on any magnet. Consists of iron filings contained in a flat, circular, clear acrylic container (similar to a petri dish, but well sealed), along with a small bar magnet and a disk/poster magnet.
MGNT.66 $7.95 each
Mysterious Magnetic Tube
Large clear acrylic cylinder containing iron filings. The cylinder has a smaller central tube where a cow magnet (included) is inserted to show the three-dimensional nature of the magnetic field.

The original magnet! Naturally-occurring iron-rich rock that is actually magnetic! Attracts paper clips, gathers iron filings & deflects compass needles. Individual pieces approximately 2 to 3 cm across.
ROCK.04 $2.00 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.

Neodymium Magnets (seconds/surplus - limited supply, when
they're gone, THEY ARE GONE)
Very powerful magnets! Please read warning/caution at the beginning of this section. Incredible "rare earth" magnets, must be seen to be believed. 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.
MGNT.13 Bent Rectangle, 0.83" X 0.738" X 0.128" thick $6.95 each

Neodymium Magnets (new, shiny finish)
Wonderfuly powerful super magnets! Please read warning/caution at the beginning of this section. Incredible "rare earth" magnets, first quality, not surplus or "seconds". Disks have a bright, shiny chrome-like finish, packaged in a clamshell/blister card. Note that all three packages are the same price, but contain different sizes and numbers of magnets (i.e. the package of largest disks has only 3 in the package, whereas the package of smallest disks has 10 in the package). WARNING: These magnets can easily pinch skin if caution is not used. Definitely NOT for young children. Ages 12+ only.
PRICING NOTICE: Unfortunately, the cost of neodymium magnets has TRIPLED recently and we are forced to pass on these price increases.

MGNT.20 Random short pieces $3.00 pkg
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.
For revitalizing old Alnico, steel bar 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 $100.00 each
