We can see that

∇x

**H**=

**J**

_{free}

and

∇x

**B**=μ

_{o}(

**J**

_{free}+∇x

**M)**

∇x

**B**=μ

_{o}(

**J**

_{free}+

**J**

_{B}

**)**

And now my question is, if K

_{B}≠ 0 , how I can't see its contribution to

**B**in the last equation?

I have been solving problems in class and in them it appears a contribution to

**B**, after using the curl theorem, like this

∫K

_{B}·dl

Thanks for your time
