HMS Magnet was originally an American brig captured by the Royal Navy in 1812 during the War of 1812. Measuring approximately 172 tons (bm), she was captured by HMS Ringdove on 18 July 1812 while sailing from Belfast to New York City, carrying passengers and a small cargo of linens. Following her capture, she was taken into British service "for the use of the King's service," indicating her repurposing for naval or auxiliary duties. Initially serving as a prison ship at Halifax, Nova Scotia, HMS Magnet's role was primarily custodial during the war. The vessel's service history is somewhat obscure, with records indicating she was renamed Attentive, possibly in 1814 when the Royal Navy acquired Sir Sydney Smith, which was renamed Magnet. As Attentive, she functioned as a store ship, still operating around the Halifax station, supporting naval logistics and supply efforts. Notably, her construction details, such as her exact design, armament, or dimensions beyond her tonnage, are not specified in the records. Her operational life with the Royal Navy was relatively brief; she sailed to Britain in 1816 and was subsequently broken up in January 1817, marking the end of her service. The available records are sparse and contain some contradictions, such as discrepancies in her burthen compared to other vessels of similar names and confusion surrounding her identity as a privateer, which is not supported by comprehensive privateer lists. Overall, HMS Magnet's significance lies in her role as a captured vessel serving in the Royal Navy during the War of 1812, primarily as a prison and store ship, before her decommissioning and dismantling shortly after the war's conclusion.
