Yondr's core product is the Yondr Pouch, a magnetic pouch in which a person's cell phone may remain in their possession but unusable within a designated phone-free area (such as a school, performance venue, meeting room, etc.).
A switchable magnetic device usually consists of a magnetic circuit with permanent magnets. By moving some parts of this circuit, the magnetic flux can be directed within the device (off position) or externally (on position). [3] One type of magnetic switchable device is made from two blocks of iron, with a round cavity bored through the center.
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]
Magnetic field induction along the axis crossing the center of coils; z = 0 is the point in the middle of the distance between coils Contours showing the magnitude of the magnetic field near a coil pair, with one coil at top and the
Magnetic confinement fusion devices exploit the fact that charged particles in a magnetic field experience a Lorentz force and follow helical paths along the field lines. [92] The simplest magnetic confinement system is a solenoid. A plasma in a solenoid will spiral about the lines of field running down its center, preventing motion towards the ...

Retort stand. In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both ...
