text: If the magnetic field is non-uniform and at different parts of the surface, the magnetic field is different in magnitude and direction, then the total magnetic flux through the given surface can be given as the summation of the product of all such area elements and their corresponding magnetic field.
text: This is valid for the moment due to any localized current distribution provided that the magnetic field is uniform.
text: Within the core the magnetic field (B) will be approximately uniform across any cross section, so if in addition the core has roughly constant area throughout its length, the field in the core will be constant.
text: MRI requires a magnetic field that is both strong and uniform to a few parts per million across the scan volume.
text: When a bar magnet is bend into the shape of a horseshoe, the magnetic field between the poles is nearly uniform and usually quite strong.
text: We often assume that the magnetic field is uniform in a region and zero everywhere else.
text: For example, if the magnetic field is uniform, so we can express it as $\mathbf B=[0,0,B_0]$, the potentials that would give the magnetic field correctly could be defined as
