Seeing Is Believing

Viewer Card Finally, a way to actually "see" DC magnetic fields from permanent magnets or magnetized metals without messy iron filings! You can use this amazing film over and over to view the location and number of poles on any magnet. Just lay the card on the magnet to see the polar pattern. Magnetic poles appear as dark areas and the light areas represent where the N and S poles meet. Flexible thin rubber magnets show up as stripes. A great inexpensive magnetic detector for finding objects in your environment that have become magnetized. Uses no batteries. Also great for science projects. Dimensions: 2-1/2" x 4"

Viewer Gel

Magnetic Field Viewer Gel

Same flat viewer material that is in the viewer card but larger (full 12" x 12") and without the lamination. Can be re-used over and over. Can be cut to custom sizes with a scissors, bent or rolled. For DC magnetic fields only.

Paper-thin and highly flexible, this viewer uses micro-encapsulation of colloidal Nickel to reveal magnetize material. In the encapsulation process, colloidal Nickel particles suspended in the slurry become engulfed within gelatinous membranes. A 2-mil layer of the magnetically sensitive slurry is bonded to a 5-mil sheet of plastic film and allowed to dry. After complete drying, the particles maintain freedom of movement within the gelatinous membranes.

When a DC magnetic field is applied to the finished film, the Nickel particles congregate in alignment with the flux lines emanating from the DC magnetic source. This clumping of nickel particles causes a darkened appearance in the film exactly where the magnetic field is impinging on the film. As a result, an exact two-dimensional image or impression of the magnetic pole or pole pattern (if there are more than one) is produced. This image is easily erased once the film is removed from the magnetic source and the nickel particles are allowed to freely re-disperse within their gelatinous cells. A common bar magnet can be swiped across the film to ensure complete erasure of the previous image, or by reapplying the film to another magnetic source the new image produced will completely replace the old one.

Because of the small size of the colloidal Nickel particles, the film can detect fields as low as only a few gauss and still produce a clear image.

Due to the film's high flexibility, it easily conforms to magnetic surfaces with high degrees of concavity and convexity. Also, because the film is so thin and can be cut down to practically any size without losing its properties, it can be used in tighter places inaccessible to the bulkier, unalterable devices. Finally, since there are no moving or electronic parts, the film never needs maintenance or repair.

Filing Viewer Remember playing with iron filings and a magnet" The magnet makes the filings stand up on end and arrange themselves in beautiful patterns according to the magnetic field lines. The problem was that the filings would stick to the magnet so hard it was difficult to remove them AND filings that spilled made a huge (and rusty) mess. This clever device solves both problems by enclosing the iron filings in a clear hard plastic case! Now students, children and adults too can enjoy learning about magnetic attraction the fun and clean way. You must supply your own magnet, but just about any magnet will do. And when you are done, just put it away in a drawer and there's nothing to clean up. 3" round.

QTC™: Quantum Tunneling Composite

QTC™: Quantum Tunneling Composite

Transforms from Insulator to Conductor with Pressure

This flexible polymer exhibits extraordinary electrical resistance change when deformed by squeezing, pulling or twisting. In practice, QTC™ can be connected in quite simple ways to create anything from switches to force sensors. In its normal, uncompressed state, QTC acts as a near perfect insulator, but as it is gradually compressed it will allow more current through until it is nearly a perfect conductor. Fun to experiment with and great for turning anything with a screw-in battery compartment into an effective dimmer switch! Can also be used between layers of conductive fabric to make variable switches and variable resistors or capacitors.

It is claimed that electrons 'pass' through the insulation by a process called quantum tunneling. In classical physics, the electrons cannot pass through an insulating barrier, but according to quantum theory a wave can - and this is what happens in QTC™. Another way of describing the quantum tunneling effect is to say that a non-zero probability exists of electrons one side of the insulation barrier appearing on the other side.

QTC™ can be used as a solid state switch - in the "off" state it is a good insulator and in the "on" state it is as good as a metal conductor. It can be used to detect even very small changes due to compression, tension or other stresses and it can carry significant currents allowing for the direct control of loads. QTC™: Quantum Tunneling Composite QTC™: Quantum Tunneling Composite

Rated for over one million compressions.
The maximum specified voltage is 40V, maximum current is 10 Amps.
Temperature variation (for a current of 1microA) shows an approximately linear increase in the resistance (R=63MOhm to R=1240MOhm) observed from 25°C to 180°C.

  Magnetic Shielding Alloys


High Saturation Magnetic Alloy

Magnet Shield

First line of defense for shielding strong magnetic fields from magnets, speakers, small transformers and motors. Strong magnetic fields are harder to shield because they tend to "saturate" the shielding material. This 4" wide foil is a hefty .010" thick and has an exceptionally high magnetic saturation of 21400 Gauss and maximum permeability of 4000. Tin plated for excellent corrosion resistance and better conductivity, it can be soldered or painted.

MagnetShield typically reduces fields up to a factor of 2 or 3 depending on size/shape of the shield. Can be used in multiple layers, and/or in combination with a higher permeability alloy such as Joint-Shield for higher attenuation. Annealing is not necessary with this material. Compare the magnetic shielding of various houshold items: Aluminum pie plates, steel cookware, Silver spoon etc.

For increased shielding effectiveness, consider the following strategies:

  • Good: Layer(s) MagnetShield
  • Better: One or more layers of MagnetShield (closest to the source of field), followed by one or more layers of a high permeability material such as Joint-Shield or MagStop Plate.

Applications Notes:

- The magnets will be attracted to the shield (this is true of ALL magnetic shielding alloys). If you want to shield 2 adjacent magnets from eachother, each magnet should have its own shield.
- The size, shape, and position of the shield all matter in terms of shield performance. For example, larger shields are better than small shields. Closer to the magnet is better than farther from the magnet. And parallel to the magnetic field lines is better than perpendicular to them.
- You will likely need more than one layer of shielding material, depending on the strength of your magnets. More layers = more attenuation.
