Very accurate measurement of small magnetic fields has only been practical since the discovery in 1988 of giant magnetoresistance in specially layered materials. This discovery in fundamental physics was quickly applied to the magnetic hard-disk technology used for storing data in computers.

Learn what solenoids are and why they're important. We will see that when we pass current through a solenoid, it produces a magnetic field similar to a bar magnet.
let's explore how to calculate the path taken by a charged particle in a magnetic field and then we'll be able to answer why these beautiful auroras are only seen by people at the poles that's right at times these people can see spectacular light shows in the sky but only happens at the poles we'll be able to answer that question later all ...
Let's explore what magnetic field lines are, why we draw them, and what their properties are. Here is the link to the simulation https://www.khanacademy.org/science/physics/discoveries/magnetic-fields/pi/tracing-a-magnetic-field
Learn how to determine the magnitude and direction of the magnetic force experienced by a charge moving in a magnetic field.
