MAGNETICS

Ferrofluid is an iron-based liquid that reacts in the presence of a magnetic field.  Comprised of nano-scale magnetic particles suspended in a transparent liquid, ferrofluid aligns itself to a magnetic field, making it easy to visualize the field. With this amazing magnetic...

Our mighty 4mm cubic rare earth magnets are incredibly useful, mesmerizing to fiddle with, and a steal for only 5 bucks for a tube of 20. We had these custom manufactured to the highest magnetization the factory could concentrate into...

These Campo del Cielo meteorites fell to Earth 4,000–5,000 years ago in  Argentina. They are estimate to be about 4.5 billion years old and likely formed during early development of our solar system. A great birthday gift for someone uncomfortable about...

A comfort meter combines the temperature measurement of a thermometer and the humidity measurement of a hygrometer to indicate the optimal balance of the two. When the needles intersect on the black region of the gauge, you know you have...

Anyone who’s worked with tiny screws knows how convenient a screwdriver with a magnetized tip can be. With this magnetizer, you can magnetize (or demagnetize) your own screwdrivers. This tool takes advantage of the magnetic moment. Think of each atom...

A compass is used to orient oneself using the Earth’s magnetic field. This lensatic compass, the type preferred by the military, are great for navigation and made to withstand the elements. There are a few differences from a basic compass....

Keep track of time in style with this magnetic hourglass. Lasting one minute (it should actually be called a minuteglass, but I digress), this "hourglass" contains ferrous sand. With a magnet hidden in the wooden base, watch beautiful stalagmites form...

This is a quick and clean way to visualize magnetic fields. The demonstrator is a transparent acrylic case that holds iron filings. When it is placed over a magnet, the field pattern can be viewed directly, or it can be...

"SCREAMING INTENSIFIES" Cicadas are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, Tettigarctidae, with two...

Length: .875" A stir bar is the magnetic bar placed within the liquid which provides the stirring action. The stir bar's motion is driven by another rotating magnet or assembly of electromagnets in the stirrer device, beneath the vessel containing...

This tool works on the same principle of a compass, but instead of aligning to Earth’s magnetic field, it was designed to align to smaller, more concentrated magnetic fields like your refrigerator magnets. It is important to know magnet’s polarity...
