WebMagnets can be used to make other magnets and things made of iron move without being touched. Something that has been electrically charged can make other things move without touching them. Things near the Earth fall toward the Earth unless something holds them up. The Earth pulls any object towards the centre of the Earth without touching it WebThe most elementary force between magnets is the magnetic dipole–dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.

electromagnetism - Does electric and magnetic field interact?
WebThe magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of … WebWhen the electromagnet's polar orientation switches, so does the direction of repulsion and attraction. In this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston. WebHow does the magnetic field interact with a charged object? If the charge is at rest, there is no interaction. If the charge moves, however, it is subjected to a force, the size of which increases in direct proportion with the velocity of the charge. oxfam toner cartridge recycling
