Magnetic field lines (video) | Khan Academy
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
Magnetic field around a straight current-carrying wire
Let's test our understanding of the magnetic field and field lines around a straight current-carrying conductor.

Direction of magnetic field due to a current-carrying circular loop
Let's test our understanding of the magnetic field and field lines due to a current passing in a circular loop.
Magnetic field lines - Khan Academy
We do that by drawing lines everywhere. We call them the magnetic field lines. And so in this video we'll see exactly how to draw these magnetic field lines, and how we read them. So to start drawing magnetic field lines the first thing we need to do is …
Measuring magnetic fields - Khan Academy
Lesson 3: Measuring magnetic fields. Are 2 magnets stronger than 1? Measure the Earth's field! Earth's magnetic field (how to measure) Force over distance. Inverse cube law (deflection method) Inverse Cube Relationship. Inverse cube law (method of oscillation) Science > …
Magnetic force on a charge - Khan Academy
Let's see if we can study it further and learn a little bit about magnetic field and actually the effects that they have on moving charges. And that's actually really how we define magnetic field. So first of all, with any field it's good to have a way to visualize it.
