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.
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.
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.
For Dummies is an extensive series of instructional reference books which are intended to present non-intimidating guides for readers new to the various topics covered. The series has been a worldwide success with editions in numerous languages.
In a now-famous talk on fusion in 1954, Edward Teller noted that any device with convex magnetic field lines would likely be unstable, a problem today known as the flute instability. [6] The mirror has precisely such a configuration; the magnetic field was highly convex at the ends where the field strength increased.
Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. [1] The process that is used for magnetic separation separates non-magnetic substances from those which are magnetic.
In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
7-inch reel of ¼-inch-wide audio recording tape, typical of consumer use in the 1950s–70s. Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film.
