I have an object that is decently thermally insulated. I want to plot how a constant cooling power of a few watts for a few minutes is going to affect the object's temperature. I need to account for how much heat is leaking in. Getting a constant cooling doesn't seem easy. If I instead use...

Thank you! I did take the curl in spherical coordinates for practice, and I got zero! I think it' correct.

Homework Statement There is a sphere of magnetic material in a uniform magnetic field \vec H_0=H_0\vec a_z, and after some calculations I got the magnetic moment vector \vec M_0=M_0\vec a_z, where M_0 is something that isn't important to my question. I am unsure if this magnetic moment vector...

\vec H=\vec B/μ \rightarrow \vec B_0/μ=μ_0\vec a_zH_0/μ and \vec H =\vec B/μ_0- \vec M \rightarrow \vec H=μ_0\vec a_zH_0/μ_0-\vec M_i=\vec a_z(H_0-M_i) Thank you!

Homework Statement A very large slab of material of thickness d lies perpendicularly to a uniform magnetic field \vec H_0 = \vec a_zH_0, where \vec a_z is the unit vector in the z-direction. Determine the magnetic field intensity (ignoring edge effect) in the slab: a) if the slab material...
