Write all the formulas to calculate magnetic flux density
atd01:
Just The magnetic field B has another name as magnetic flux density. This is because flux = B x Area (more accurately represented in integral form by the way) Therefore, B = Flux/Area. Hence the name flux density ;)
Can we use this formula to find flux density? B=n(mu naught)I
Not actually, because it depends on area. That's why I said use the integral equation
I'm going to post a question...in which that formula is used...can u check it plz
Yes, I'll try if I know

B=πBr[arctan(2z4z2+L2+W2LW)−arctan(2(D+z)4(D+z)2+L2+W2LW)]
Formula for cylinder magnet flux density
Formula for the B field on the symmetry axis of an axially magnetised cylinder magnet (disc or rod):
\begin{aligned}B &= \frac{B_r}{2}\left(\frac{D+z}{\sqrt{R^2+(D+z)^2}}-\frac{z}{\sqrt{R^2+z^2}}\right)\end{aligned}B=2Br(R2+(D+z)2D+z−R2+z2z)
Formula for sphere magnet flux density
Formula for the B field on the symmetry axis of an axially magnetised sphere magnet:
\begin{aligned}B &= B_r\frac{2}{3}\frac{R^3}{(R+z)^3}\end{aligned}B=Br32(R+z)3R3
