We see that the self- inductance of the toroid in this limit has the same form as that of a solenoid. Example 11.4 Mutual Inductance of a Coil Wrapped Around a Solenoid A long solenoid with length land a cross-sectional area Aconsists of N1turns of wire. An insulated coil of N2turns is wrapped around it, as shown in Figure 11.2.4. 11-8 Inductance and Inductors. Disclaimer: These lecture notes are not meant to replace the course textbook. Self Inductance. An inductor is a circuit element that stores magnetic field.Hi, using this calculator http://qrp.gr/jlab/calculators/permeability_calc.htm it seems that the desired inductance can be accomplished usind different cores with differend permeability materials...In this video I will find the self inductance of a toroidal solenoid.
Toroid is form when you have wound conductor around circular body. In this case you have magnatic field inside the core but you dont have any poles because circular body dont have ends. This can be used where you want minimum flux leakage and dont need magnatic poles. i.e. toroidal inductor, toroidal transformer.

There are several factors that have a direct bearing on the effective permeability of a ferrite rod, which in turn will effect inductance and 'Q', as well as the A L value of the rod and its ampere-turns rating. These are: (1) Length to diameter ratio of the rod, (2) Placement of the coil on the rod, (3) Spacing between turns and, (4) Air space ... Capacitance Inductance J = 0.5 V 2 C J = 0.5 I 2 L J = joules of energy stored V = peak charge voltage I = peak current C = capacitance in farads L = inductance in henries Peak values of V and I are stated in order to emphasize not to use RMS values. The energy stored at any given time is of course: From Amost All Digital Electronics, the L/C Meter IIB is a hand-held, digital inductance and capacitance meter with a sixteen character LCD with four digit resolution in each mode. Thus the maximum resolution for inductance is one nanohenry (1 nH) and for capacitance one tenth of a picoFarad ( 0.1 pF).
