"Magnetic filtration has dramatically cleaned up our fluids and improved the area complete we will offer. It extracts around 50Kg each day of ferrous waste."
Alexander Neckam, by 1187, was the main in Europe to describe the compass and its use for navigation. In 1269, Peter Peregrinus de Maricourt wrote the Epistola de magnete, the initial extant treatise describing the Homes of magnets.
Electric powered field lines can begin and close with a cost, but no equivalent magnetic charge has become identified in spite of lots of searches for so-termed magnetic monopoles.
BuyMagnets.com provides a array of neodymium disc magnets which have been of large-temperature material, which can stand up to increased temperatures without the need of losing power.
one⁄two inch reels on PET movie backings. Reasonably priced reel-to-reel tape recorders were being commonly used for voice recording in the home As well as in educational facilities, together with dedicated types expressly created for enterprise dictation.

"[10] The eleventh-century Chinese scientist Shen Kuo was the very first particular person to put in writing—while in the Dream Pool Essays—in the magnetic needle compass and that it improved the accuracy of navigation by employing the astronomical idea of correct north.
Because the tape moves about the recording head, The top's magnetic discipline varies Using the sound So varying the magnetism within the passing particles of metallic oxide over the tape.[eleven]
The nice useful benefit of tape for studios was twofold: it allowed a efficiency to become recorded without the thirty-moment time limitation of the phonograph disc, and it permitted a recorded efficiency to generally be edited or erased and re-recorded again and again on the same bit of media without any squander.
