Since the magnetic Lorentz force is always perpendicular to the magnetic field, it has no influence (to lowest order) on the parallel motion. In a uniform field with no additional forces, a charged particle will gyrate around the magnetic field according to the perpendicular component of its velocity and drift parallel to the field according to its initial parallel velocity, resulting in a ...
Today, torchère lamps use fluorescent, halogen, or LED light bulbs. Adjusting the pulse-width modulation in the electronic ballast can allow the fluorescent torchères to be dimmed. Halogen torchères usually came with a simple switch. Some more expensive models have a TRIAC dimmer circuit built into the stem. Early lamps with 300W bulbs ...
The Arco lamp is a modern floor lamp designed by brothers Pier Giacomo and Achille Castiglioni for Flos in 1962. [1] The lamp is characterized by a suspended spun aluminum pendant attached to an upright block of Carrara marble via a cantilevered arching arm made of stainless steel.

The joints and spring tension allow the lamp to be moved into a wide range of positions which it will maintain without being clamped. [3] [4] Carwardine applied to be a patent, number 404,615, [5] for a design using the mechanism on 4 July 1932, and manufactured the lamp himself in the workshops of his own company, Cardine Accessories, in Bath.

The electron mobility is defined by the equation: =. where: E is the magnitude of the electric field applied to a material,; v d is the magnitude of the electron drift velocity (in other words, the electron drift speed) caused by the electric field, and
A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
where is the slow drift motion and represents fast oscillations. Now, let us also assume that x 1 ≪ x 0 {\displaystyle x_{1}\ll x_{0}} . Under this assumption, we can use Taylor expansion on the force equation about x 0 {\displaystyle x_{0}} , to get:
