HI All !
Can somenone inform how to calculate the reluctance of a ferrite rod in free space?
It should be noted that the magnetic circuit has 2 reluctances: one provided by the ferrite rod itself Rrod, and other provided by the air gap (big) located between the ends of the rod.
So far wath Im gessing,
The total reluctance is Rrod + Rair
Rrod = Lrod/(Uini x 4x pi x 0.0000001 x Arod)
Rrod is the reluctance of the ferrite rod alone [AE/Wb] Rair is the reluctance of the space between the two extreme ends of the rod, [AE/Wb] Lrod is the lenght of ferrite rod [m], Uini is the initial permissivity (relative) of the ferrite Arod is the cross section area of ferrite [m^2]
So far so easy.
Rair = reluctance of the magnetic circuit by air between the extreme ends of the rod. Here Is the issue I ned the help!
