Magnetic Fields Around Current Carrying Wires

The video tutorial explores magnetic fields, focusing on those formed around current-carrying wires. It begins with an introduction to magnetic fields and their representation through field lines. The tutorial then explains how magnetic fields are produced by currents in wires, using the corkscrew rule to determine field direction. It also covers how the direction of current affects the magnetic field's orientation and discusses factors like current magnitude and distance from the wire that influence field strength.

Illustrate how plotting compasses can be used to visualize the direction of the magnetic field around a current-carrying wire.

Summarize the relationship between current direction and magnetic field direction using the examples provided.

What effect does the distance from the wire have on the strength of the magnetic field?
