Question:

all atoms have moving electric charges. Why, then. arent all materials magnetic?

all atoms have moving electric charges. Why, then. arent all materials magnetic?

Answer:

Moving electric cahrges do have magnetic fields. Spinning electrons also do have magnetic fields. Different planes of orientaitation of orbits make the subtances as para ,dia and ferro magnetic substances.
because not all materials are made of ionic bonds. which tends to loose electrons referring to the periodical table you will realize that elements from the left to right tend to lose electrons to be stable. the noble gases are stable and doesn't easily form bonds because their out most shells are filled (valency electrons) on like the alkaline earth metals. therefore the magneticy of a substance or materials depend on the elements its made of! hope that helped!
Because all atoms (most atoms) contain both electrons (those moving electric charges - negatively charged) and a core containing protons (the positively-charged counteractive force) so their overall charge is neutral. Ions are atoms where the electron count does not equal the proton count, either greater or lesser, and therefore do have a charge. Now some molecules, happen to orient their joint electron fields so that the electrons spend more time along one side of the molecule than the other, so even though they may be neutral in total charge, they do have a positive and negative bias.
