Maximum Flux Density Calculator

See our other Electronics Calculators.

The maximum flux density for a core/coil geometry should be calculated to verify that it is below the specified value for a given core, so that the core doesn't saturate.  This calculator is useful in matching a core size to the required power.  

Note that if there is no DC term, then the calculation is completely independent of the core material.  

 

AC Terms
Vrms (Vrms)
F (frequency, use the minimum frequency that the coil will see) (MHz)
N (Number of turns)  
Ac (Equivalent area -  the cross section of core) (cm2)
Optional DC Terms.
Idc (DC current through winding. This is optional) (A)
L (Specific to core used. Only enter if, coil has DC) (uH)

Bmax (gauss)

Equations

Bmax=Bmax(AC)+Bmax(DC)

Bmax(DC)=  (L*Idc*108)/(NAc)

Bmax= (Vrms*108)/(4.44*F*N*Ac) + (L*Idc*108)/(N*Ac) gauss

Note if no DC current flows, then the second term of the equation is dropped. 

In terms of AL(uH/100T2):

L= N2AL(uH/100T2)10-4

Bmax(DC)=  (N*AL(uH/100T2)104*Idc)/(Ac)
