Solenoid Magnetic Field (10:11)
Good morning, physics enthusiasts! Today on Flipping Physics, we're delving into the fascinating realm of ideal solenoids, those remarkable tools for generating a uniform magnetic field. Join us as we explore the anatomy of a solenoid, unraveling its structure of a single, insulated wire coiled to form a hollow cylinder. In the world of ideal solenoids, length dwarfs diameter, creating a magnetic wonder. As we embark on the journey to understand the magnetic field within this device, witness the application of the alternate right-hand rule and the emergence of an Amperian loop. Dive deep into the derivation using Ampère’s law, demystifying the equation for the magnetic field inside an ideal solenoid.
