Magnetmuseum
The magnetic Museum is a private museum in Dortmund technical magnet, which has existed since 1999. It is located in Aplerbeck district on the premises of the group Tridelta that at the location - in succession Magnetfabrik Aplerbeck the Aplerbecker hut - inter alia Permanent magnets made .
History
Museum
The museum opened on 27 August 1999 at the Tridelta factory premises. It is essential for the development of the collection and the existence of the museum was and is the involvement of two former employees of the magnet factory. In October 2005, the magnetic museum was closed for operational reasons. After new premises on the Tridelta factory premises were found, it was re-opened on June 20, 2013 in the former premises of the Executive Board of the German steel works.
Since 2013, the museum is regularly open two days a week; Admission is free. There are also guided tours.
Exhibition
The collection of the museum magnet consists of around 35 tons of exhibits, some of which is, however, stored in the basement.
The permanent exhibition provides an overview of historical and current applications of permanent magnets, particularly in electrical engineering. Is illuminated next to the historical development of permanent magnet materials, among others the use of permanent magnets in meters, loudspeakers, telephones, switches, relays, clocks, gauges, small motors, generators and brakes such as Hysteresis. One focus of the exhibition is also the varied history of the magnet factory Aplerbeck.
Magnetfabrik
The Aplerbecker Tridelta plant ( Tridelta Dortmund GmbH and Tridelta Magnet Systems GmbH) goes back to the magnet factory Aplerbeck the Dortmunder Union, which began as part of the Aplerbecker hut with the Magnetbau 1920 and initially va AlNiCo permanent magnets produced. Following the closure of Aplerbecker hut Magnetfabrik 1927 became part of the newly founded German stainless steel Werke AG ( DEW ). In the 1930s, the industrial demand for magnets, including for the production of popular receivers, speakers, and field telephones. From 1938 to 1940, the DEW built a new factory and office building with brick facade, which consists of a core to this day. In Magnetfabrik temporarily worked up to 1700 people.
1975 or 1976 was the DEW on in the Thyssen steel works ( TEW ); the Aplerbecker Magnetfabrik then became part of the Thyssen group.
In the 1990s, the areas of magnet production and trade were separated via several intermediate steps, so that now two different companies - Tridelta and ThyssenKrupp Schulte - refer in their history on the Aplerbecker magnet factory.
1992 merged the Thyssen- ranges of stainless steel and steel; the magnetic field went to the electrical steel company Bochum ( EBG ) and operated under magnetic Thyssen GmbH. In 1997, the magnetic field was ( temporarily as MTG Magnet Systems GmbH ) to the Thyssen Stahl Union. At ThyssenKrupp focused on the distribution of magnetic materials, systems andf components, including the Thyssen was refounded magnetic and components GmbH. The actual magnet production in Aplerbeck in 1997 sold to the Hermsdorfer Group Tridelta GmbH, which has its origin in the Thuringian VEB Kombinat Ceramic Works Hermsdorf ( KWH ) has. Tridelta erected at the sites Aplerbeck continues to produce permanent magnets for the electrical industry.
The 1997 split Thyssen- magnetic trading division drew first round in 1998 by Aplerbeck to Dortmund - Dorstfeld. As of 2002, it operated under the name ThyssenKrupp Magnet Technology GmbH and then moved 2003 to Gelsenkirchen. In 2005 it was incorporated as a business magnet technology in the ThyssenKrupp Schulte GmbH, which goes back again to the Dortmund-based company Heinrich August Schulte. 2010 Finally, the company moved to Essen.
