Magnetic Force — Premium & Premium

Two North poles or two South poles will push each other away. 3. The Field

Most of our technology relies on magnetic force to convert electrical energy into motion (motors) or motion into electricity (generators). magnetic force

Hard drives use tiny magnetic signatures to "remember" 1s and 0s. Two North poles or two South poles will push each other away

Magnetic force is responsible for more than just sticking notes to a fridge: magnetic force

Magnetic fields are created whenever electric charges (like electrons) are in motion.

When current flows through a wire, it creates a magnetic field around that wire. This is the principle behind electromagnets. 2. The Rules: Opposites Attract Every magnet has two poles: North and South . Attraction: North and South poles pull toward each other.
