Geomag, stylized as GEOMAG, is a magnetic construction toy consisting of a collection of bars, each set with a neodymium alloy magnet at both ends, connected by a magnetic plug coated with polypropylene, and nickel-coated metal spheres. These elements interlock using magnetism, allowing for them to be assembled in various ways.
Magnetix is a magnetic construction toy that combines plastic building pieces containing embedded neodymium magnets, and steel bearing balls that can be connected to form geometric shapes and structures.

Rather than the rods of Geomag, Magnext has 'triangular' and 'square' pieces with 3 and 4 embedded magnets. The balls are 0.59 inches in diameter (larger than the 0.50 inch balls of Geomag). Being one of MEGA Brands' last attempts at the magnetic toy business the company made small figures in some sets out of a strong and lightly stretchy rubber.
The permeability of vacuum (also known as permeability of free space) is a physical constant, denoted μ 0. The SI units of μ are volt-seconds per ampere-meter, equivalently henry per meter. Typically μ would be a scalar, but for an anisotropic material, μ could be a second rank tensor .
1.256 637 061 27 (20) × 10 −6 n⋅a −2 The vacuum magnetic permeability (variously vacuum permeability , permeability of free space , permeability of vacuum , magnetic constant ) is the magnetic permeability in a classical vacuum .
CircuitMaker is electronic design automation software for printed circuit board designs, for the hobby, hacker, and maker community. [1] [2] CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. [3]
This equation is valid for a solenoid in free space, which means the permeability of the magnetic path is the same as permeability of free space, μ 0. If the solenoid is immersed in a material with relative permeability μ r, then the field is increased by that amount: =.
