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.

Master Tracks Pro (MTP) is music-sequencer software for Windows, to author and/or edit MIDI data. David Kusek and Don Williams et al. at Passport Designs originally created it, continuation of marketing and development by GVOX, and, as of Aug. 8, 2013, by Passport Music Software, LLC.
When the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect.To simplify the analysis, and because the other two configurations have vanishing Kerr rotation at normal incidence, near normal incidence is usually employed when doing experiments in the polar geometry.
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 .
For example, 4% electrical steel has an initial relative permeability (at or near 0 T) of 2,000 and a maximum of 38,000 at T = 1 [5] [6] and different range of values at different percent of Si and manufacturing process, and, indeed, the relative permeability of any material at a sufficiently high field strength trends toward 1 (at magnetic ...
