Governing Equation
Magnetostatics is the study of magnetic fields in devices where the magnetic field is generated from DC (steady) currents and/or permanent magnets. Magnetostatics is a special case of Maxwell’s equations, which form the basis of electromagnetism.
For magnetostatics the electric field inside of a current carrying coil is completely decoupled from the magnetic field, and the following Maxwell’s equations are solved for magnetostatics -
Where∇denotes divergence, H is the magnetic field intensity, J is the current density and B is the magnetic flux density.

A few words on the formatting on the following instructions:
Notes that require you to perform an action are colored in blue
General information will be colored in black, but do not require any action
Words that are bolded are labels for items found in ANSYS AIM
Most important notes will be colored in red
Now that the the pre-calculations are finished, we are ready to begin the simulation in ANSYS AIM. Open ANSYS AIM by going to Start > All Apps > ANSYS 18.2 > ANSYS AIM 18.2. Once starting page has opened, select the Magnetics template as shown below.
