An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence ...
MagneRide is an automotive adaptive suspension with magnetorheological damper system developed by the Delphi Automotive corporation, [1] [2] that uses magnetically controlled dampers, or shock absorbers, for a highly adaptive ride. As opposed to traditional suspension systems, MagneRide has no mechanical valves or even small moving parts that ...
Voice coils wound with flattened wire, called ribbon-wire, provide a higher packing density in the magnetic gap than coils with round wire. Some coils are made with surface-sealed bobbin and collar materials so they may be immersed in a ferrofluid which assists in cooling the coil, by conducting heat away from the coil and into the magnet ...
Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
The REO Motor Car Company was a company based in Lansing, Michigan, which produced automobiles and trucks from 1905 to 1975. At one point, the company also manufactured buses on its truck platforms. Ransom E. Olds was an entrepreneur who founded multiple companies in the automobile industry.
As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
These "slick-top" cars mount their emergency lights within the cruiser, generally around the periphery of the windshield or into the leading or trailing edge of the roof. Slick-top police cars also lack the silhouette of a lightbar or beacon, making the car harder to identify as a police vehicle from a distance, especially fore and aft.
Second order magnetic gears use a ratio of magnetic pole pairs between inner and outer magnetic rotors, where the rotor with fewer magnets rotates at a higher rate than the rotor with more magnets. An intermediate ferromagnetic pole "stator" is usually held stationary between the rings, to direct the concentration of the magnetic lines between ...
