polymer like cellulose acetate or polyurethane, that has the magnetic pigment pigments embedded in it. The top coat is fairly skinny and ranges from 2um-13um in cross-sectional length.
Poulsen later on made other magnetic recorders that recorded on the metal wire, tape, or disks. None of these equipment experienced electronic amplification, even so the recorded signal was conveniently powerful plenty of to get read via a headset or transmitted on telephone wires.
In document manner, the coil gets to be an electro-magnet, generating a magnetic discipline various with electrical current equipped by a minimal-power amplifier hooked up to an audio supply such as a microphone.
Remagnetization — Neodymium magnets can be employed to put the magnetization back again in other kinds of magnets, such as Alnico horseshoes as well as other bar magnets.
Neodymium magnets have a variety of purposes throughout several industries, due to their extraordinary magnetic power and versatility. Some widespread works by using of neodymium magnets consist of:
