The magnet is Axial magnetised (Through the 12.5mm height) Identified by the AMF part number 39091.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eUses for our samarium cobalt block magnets:\u003c\/h3\u003e\n\u003cp\u003eA compass, first used around 1200AD, was the original block magnet. Rectangular or filaments of a naturally occurring mineral, lodestone, discovered seven hundred years earlier by ancient Greeks, was suspended and allowed to turn from the rigging of Chinese and Viking sailing ships. This block of rock always points north. For the early mariners, and still today, this is a deeply helpful piece of technology.\u003c\/p\u003e\n\u003cp\u003eThese types of block magnets, a combination of samarium, cobalt and iron were first produced in 1970 and since that time have been deployed in a wide range of applications across a vast swath of human interests.\u003c\/p\u003e\n\u003cp\u003eThese magnets are very strong relative to their size. They are chosen where space is a premium. These spaces include computer disc drives, sensors, satellite systems, tools and trinkets to name a few. Samarium cobalt blocks are also deployed in pickups on stringed instruments.\u003c\/p\u003e\n\u003cp\u003eA pickup device is a traducer, a method of converting variations of one quality into those of another. Installed on guitars and violins, pickups sense mechanical vibrations inside its magnetic field, created when the strings are struck or plucked.\u003c\/p\u003e\n\u003cp\u003ePickups are able to then convert these captured vibrations into an electrical signal and then amplified to produce musical sound. Samarium cobalt blocks are very strong, need to be handled with care and not allowed to jump at an attracting object.\u003c\/p\u003e\n\u003cp\u003eUsed for a large variety of purposes such as in the manufacture of RFID tracking systems, downhole tool systems, general line can maker, tinplate printing and for situations where resistance to salt and corrosive environments is essential.\u003c\/p\u003e","brand":"AMF MAGNETICS","offers":[{"title":"Default Title","offer_id":53866579853678,"sku":null,"price":89.47,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/9844\/8037\/files\/22005_2_1200x_2x_1.jpg?v=1780368101","url":"https:\/\/magnet.com.au\/products\/samarium-cobalt-smco-block-magnet-50mm-x-50mm-x-12-5mm","provider":"AMF Magnetics","version":"1.0","type":"link"}
