Current makes magnetic fields

Current makes magnetic fields

Magnetic field patterns for a straight wire, a flat circular coil, and a solenoid with labels and arrows

Electromagnetism links electricity and magnetism: moving charge produces magnetic fields. Current III is the flow of electric charge, measured in amps (A), and a current-carrying conductor creates a magnetic field around itself.
