Magnets positive negative
WebThe world is full of ions, both positive and negative. Positive ions are always being absorbed throughout the day, causing various physical effects on the body. ... Magnets are based on two polarities; Positive and … WebField lines represent the force a positively charged particle would experience if it were in the field at that point. A changing magnetic field can also cause electric charges to move. This phenomenon is commonly used in electric generators to induce electric currents in wires.
