How to assign the formula , to find differnt parameters of coil , suppose i want to find the magnetic flux density of coil by using the following formula ,
B = u0*NI*R^2/2(R^2 + d^2)^1.5 , where u0 is permeability of medium , N and I are No.of turns and Current in the coil respectively , d is distance between the point of coil1 to point of coil 2 , how to insert these formula , to find the magnetic flux density in the coil
I simulated by giving simple coil and exicited by the multiturn coil in 2D symetric case , but If i take radius is 0.35m and current of coil 1 A , at d = 0 , i should get H= 1.42 A/m , but i am not getting and getting less ...could tell the what is
problem and solution
Model is attched
