Ampere’s circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.” Watch the Video and Learn about Magnetic Field Due to Solenoid and Properties of Magnetic Field Lines ...
To generate a magnetic field, moving charges in an electric conductor are needed. Once electric current passes through a wire, loop, or solenoid a magnetic field is generated and can be found in the surrounding area by using a compass. The compass needle will point in the direction of the...
