The Racecourse Colliery
The Racecourse Colliery is an exhibit located at the Black Country Living Museum. Original mine shafts at the Black Country Living Museum The Black Country Living Museum has more than 40 old mine shafts on its site, which have largely been lost, in-filled, collapsed, stabilised or capped. One of the original surviving shafts has been used to create the Racecourse Colliery exhibit. It was originally the shaft of one of the Earl of Dudley's small pits, Coneygree Colliery Pit No 126, which operated between 1860 and 1902. After the pit was abandoned, all the surface landmarks were removed and the shaft itself was eventually filled in. Work started on the creation of the Racecourse Colliery exhibit in 1979 and, with the exception of the head frame, all work was carried out on Sundays by volunteers from the Birmingham Enterprise Club and the Friends of the Black Country Museum Mining Group. The colliery was re-created following exactly the same sequence as the creation of an actual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

An electromagnetic coil is an electrical Electrical conductivity, conductor such as a wire in the shape of a wiktionary:coil, coil (spiral or helix). Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, Electric generator, generators, inductors, electromagnets, transformers, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external ''time-varying'' magnetic field through the interior of the coil generates an Electromotive force, EMF (voltage) in the conductor. A current through any conductor creates a circular magnetic field around the conductor due to Ampere's circuital law, Ampere's law. The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current. The magnetic fields generated by the separate turns of wire all pass throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
