magnetic materials and electric currents (moving electric charges) are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources.Can someone give me some explanation on this? Or something that can help me comprehend this?Any other information? Thank you.
magnetic materials: such as pieces of iron that have been magnetized, refrigerator magnets, etc electric currents: electricity moving down a wire each have, or create, magnetic fields (the area next to the magnet, and the wire, where the magnetism exists) are subject to forces: can be effect by (subject to) other magnets (and active electric wires) that happen to be near enough.
