Magnetic field due to current-carrying coil When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Magnetic effect of electric current is one of the major effects which functions as the basic principle in appliances used in various fields of activities.
