Toroidal inductors are used where large inductance are required at low frequency levels. These are insulated coils in ring shape. As toroid inductors have more number of turns it can carry more currents.The wire gauge affects inductance only indirectly, since the wire size determines how many turns you can wind on a given toroid and, of course, inductance is proportional to the number of turns. I have a Toroid Core listed here: LINK , i have T130-52 . Now i need to build an inductor out of this toroid. How do i determine which wire to wound, and how many turns would give me what inductance?

The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Solenoid and toroid both work on the principle of electromagnetism and both behave like an electromagnet when current is passed. The magnetic field produces by them is B = Uo.ni. Even after having so many similarities solenoid and toroid differs in property such as shape: 1. A solenoid is cylindrical in shape whereas toroid is circular. 2.
