Magnet Museum

The Magnet Museum stands in Dortmund-Aplerbeck, a district in the city of Dortmund within the Regierungsbezirk Arnsberg. It is a private museum owned by the company Tridelta. The building houses a collection dedicated to the history and modern uses of permanent magnets in electrical engineering. Exhibits trace how magnets power everyday devices from counters and speakers to telephones and small motors. The museum also explores their role in generators and measuring instruments.

The museum’s displays highlight the significance of Dortmund’s own magnet factory, founded in the 1920s. This factory helped shape the region’s industrial identity through its production of permanent magnets. Visitors learn how the company’s innovations influenced electrical engineering across decades. The collection reflects both historical milestones and ongoing technological progress. It offers a focused look at a material often taken for granted but essential to modern life.

Inside, the museum arranges artefacts chronologically, guiding visitors from early experiments to contemporary applications. Each section explains how magnets function within specific devices. Labels describe materials like alnico and neodymium that define different eras of magnet technology. The surroundings include workshop-style displays and hands-on models. Outside, the building sits among quiet residential streets, its presence subtly marking the area’s industrial heritage.
