Magnetic Field using Biot-Savart law: Circular Loop and Long Wire

Physics Ninja looks at the Biot-Savart law and uses the law to calculate the magnetic field produced by a current loop. In the second example i show how to evaluate the field produced by a long wire. For the long wire i show how to solve using trigonometric substitution and also using integral tables. Visit my Etsy store and support Physics Ninja: https://physicsninja.etsy.com
