Fishing with magnets, also known as magnetic fishing, is the act of searching external waters for magnetic objects that are available to be triggered with a strong neodymium magnet.
This hobby, which is a combination of environmentalism and treasure hunting, has grown rapidly in the UK and the US in recent years and requires almost no technical knowledge to begin with. The only equipment needed for magnetic fishing is a powerful magnet with a loop or an eye attached to it, a strong rope, a pair of gloves and something to put any metal object you can find.

MAGNETIC FISHING
The magnets used are strong enough to remove large debris such as discarded bicycles and water body car rims, but many who devote themselves to the hobby hope to find rare and valuable items, including historical relics and modern appliances. Magnet recovery tools are specially designed to recover items that are lost at the bottom of bodies of water, with rivers, lakes and streams being typical places for fish magnets. Canals are also a popular spot for fish magnets, due to the large number of items casually discarded in them over the past few centuries.

Historical relics such as ancient weapons were previously found by those who took part in this pastime and earlier this month and an unexploded World War II bomb was unearthed in Northamptonshire. In November last year, a woman fishing in Wales pulled a World War II bomb out of a canal, and in 2015 a boy pulled a World War II grenade that did not explode from London's Grand Union Canal, which posed risks to those involved.
