The galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component B H of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electric current flows through the galvanometer coil, a second magnetic field B is created. At the center of the coil, where the ...
Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
There was what might be called a concertina craze on: innumerable coils of barbed wire were converted into concertinas by the simple process of winding them round and round seven upright stakes in the ground; every new lap of wire was fastened to the one below it at every other stake by a twist of plain wire; the result, when you came to the ...
From top: Spade, brad point, masonry, and twist drills bits Drill bit (upper left), mounted on a pistol-grip electric drill A set of masonry drills. A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of ...
It is composed of a rule and one or more interchangeable heads that can be attached to the rule. [1] [2] Other names for the tool include adjustable square, combo square, and sliding square. The most common head is the standard head, which is used as a square for marking and testing 90° and 45° angles. [3]
A Helmholtz coil Helmholtz coil schematic drawing. A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis, carrying an equal electric current in the same direction. Besides creating magnetic fields, Helmholtz ...
A security Torx L-key and fastener with holes for a safety pin to hinder disassembly with an ordinary Torx key. A Torx T8 screw head on a hard disk drive.. Torx (pronounced / t ɔːr k s /) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 [1] by Camcar Textron.
Blade micrometers have a matching set of narrow tips (blades). They allow, for example, the measuring of a narrow o-ring groove . Pitch-diameter micrometers (aka thread mics ) have a matching set of thread-shaped tips for measuring the pitch diameter of screw threads.
