Hi Adnan, a kernel is somewhat where you can wind the wire on. It may be a round peace of plastic with a diameter of 6 mm in this case. Your store will offer such material possibly in different sizes and diameters. Some may have a screw of ferrit inside for the sake of adjusting the iductivity. Possibly you can remove this ferrit and throw it away. In addition your ask for wires of the respective diameters which you may get wounded on bobbins. The wire lenght depends on the diameter of the wire and the bobbin and can be 100 m for very thin wire and 5 to 10 m for thick wires. Ask your store for details.

Just one more question, since I am doing hardware project the first time, could you please tell me what a kernel is and what I should say to the hardware store owner, "give me some wire to make inductors" or "give me a coil with the dimensions x,y,z" . Please help. Adnan Yusuf --- In [email protected], "Bodo J.
