I want to know if there is such a symbol (i.e. an electrical diagram symbol for an inductance with a magnet as a core). If such is the case how is it specified the orientation of the poles of the magnet? Thanks in advance

  • \$\begingroup\$ Isn't a coil with a magnet inside it called a motor...? Or a Moving Coil Panel Meter...? \$\endgroup\$

  • \$\begingroup\$ then you are saying guitar pickups are a motor (or a moving coil panel meter). \$\endgroup\$ Nov 17, 2016 at 1:40
  • \$\begingroup\$ No, a guitar pickup is a guitar pickup. I'd have thought that was obvious. The point I am making is that you put the device in the schematic, not what it is made of. \$\endgroup\$

  • \$\begingroup\$ Often the datasheet will have some form of symbol on it you can use as a basis for your own symbol. What does the datasheet of your mystery component say? \$\endgroup\$

  • \$\begingroup\$ there is no datasheet because its a "custom" (hand-made) coil. We used two of them and each one had a magnet. There is no special need to say in the diagram what was the magnet made of, but yes its orientation. I got around the problem putting a red and blue bar beside the inductances. Thanks \$\endgroup\$ Nov 17, 2016 at 4:01

Schematics are Logic diagrams and do not indicate the material or all specifications just par numbers . If you wish to convey this information, be creative. or add to the notes.
