🧲 Welcome back to Flipping Physics! Today, let's unravel the mysteries of Ampère’s law, the magnetic field counterpart to Gauss’ law in electricity. Ampère’s law, using a closed loop integral, relates the magnetic field to the current inside an Amperian loop. Drawing inspiration from Gauss’ law, we dive into an example to determine the magnetic field magnitude outside an infinitely long, straight wire. Witness the application of the alternate right-hand rule and the clever use of B ds cosine theta. Together, we derive the magnetic field equation, showcasing its dependence on distance. 🧲📚 Want Lecture Notes? www.flippingphysics.com/ampere...
