We know that a current loop created a magnetic field similar to that of a bar magnet, but what about a straight wire? We can use the Biot-Savart law to answer all of these questions, including determining the magnetic field of a long straight wire.

We first consider arbitrary segments on opposite sides of the loop to qualitatively show by the vector results that the net magnetic field direction is along the central axis from the loop. From there, we can use the Biot-Savart law to derive the expression for magnetic field.

It examines the behavior of internal magnetic fields and their forces, including fringing fields and energy density. Additionally, it discusses magnetic fields' application in MEMS switches, detailing how magnetic pressures and the Lorentz force law facilitate current-induced movements in a beam, enabling logical functions in these devices.
