Flux means the rate of change of magnetic field lines through a particular region in space. Magnetic field lines are imaginary lines drawn to demonstrate the magnetic field through a region in space. No flux condition means the magnetic field lines in the observed region in space is uniform throughout the experiment.
All materials with atoms containing electrons (i.e. just about all materials that we ever encounter) have the properties of a diamagnet. A naive picture of what's happening is that the orbiting electrons in the atoms create a magnetic field in response to an external magnetic field that repels the external field. The property of diamagnetism is universal - it even exists in paramagnets such as Samarium Cobalt magnets. The fact that we don't notice it much is that it is weak - about a thousand times weaker than strength of a paramagnetic material.

Convection takes place through a material medium between source and sink. There isn't any material medium between sun and earth, and we are therefore thankful that radiation exists.
No material exists that doesn't conduct electrical charges at all. We call materials that conduct electrical charges poorly insulators; a material that didn't conduct electricity at all would be a perfect insulator.
Magnetic field
It's called magnetism.
The characteristic that exists in magnets but not in non-magnetic materials is the presence of magnetic domains, which are regions within the material where the atomic magnetic moments align in the same direction. This alignment leads to the overall magnetic behavior observed in magnets, such as attracting or repelling other magnetic materials.
Domains are aligned.

Magnetic fields are generated by electric current, hence magnetic forces would be an electrical property, not a mass property. Gravity is the force that exists between two masses.However, materials have magnetic properties based upon their chemical composition, for example iron metal maybe magnetised, that is a property of that material (note material, not mass).A piece of iron may be magnetised regardless of its mass (1kg or 1g or 1 tonne), as magnetism is not mass related.However, I believe what you are trying to ask is whether magnetism is a property of the material, not the mass, in which case, yes, it is a property of the material, based upon its chemical composition.
Before discovering that rocks are imprinted with the direction of magnetic orientation that exists at the time of their creation, no proof existed to confirm Wegener's hypothesis. When rocks were examined from both sides of the Mid-Ocean Ridge, the magnetic orientations were found to be mirror images of each other, indicating that the seafloor was spreading outward, and therefore pushing the continents apart.

A magnetic field is induced by moving electric charges, either by an actual electric current, or the way that electrons (charged particles) spin around the nucleus [in the case of magnetic materials becoming magnetized].
An electric current produces a magnetic field around wires where the current exists.
