Magnetic Field Detection System

The magnetic field detector system is a system which detects the presence of magnetic field in the nearby region and alerts the user by using a buzzer. This system provides an efficient way to detect magnetic field in the region and can be employed in any field according to the requirement.

The project is build using a LM358 IC and the principal on which this project works is electromagnetic induction in which when a current carrying conductor is formed into a loop or several loops to form a coil, a magnetic field develops that flows through the center of the loop or coil along its longitudinal axis and circles back around the outside of the loop or coil. The magnetic field circling each loop of wire combines with the fields from the other loops to produce a concentrated field down the center of the coil.
