HMS Magnet was a Cruizer-class brig-sloop built at Robert Guillaume’s yard at Northam and launched in 1807.

Magnet was in company with the frigate Salsette when they, together with the boats of Centaur and Implacable, captured four Russian vessels carrying corn.

[2] On 20 August, Salsette, the ship sloop Ariel and Magnet joined the squadron under Samuel Hood in Centaur, which was blockading the Russian fleet in Rogerwick Bay.

The bulk of the British fleet, including Saumarez, then departed Karlskrona for Britain, arriving in the Downs on 8 December.

Magnet then pursued Paulina throughout the afternoon and finally caught up with her at dusk about two miles off the north end of Bornholm.

[6] The convoy sought shelter off Falsterbo on Christmas Day and remained there until 6 January 1809 when the vessels set sail in an attempt to reach Malmö.

[9][10] Morris managed to get his entire crew of 120 safely ashore and they eventually arrived in Gothenburg; Magnet was a complete loss.
