Magnetic Fields and Induced Voltage

The video tutorial explains the concept of induced voltage, focusing on how moving a wire through a magnetic field can generate a current. It covers the Lorentz force, charge separation, and the derivation of the induced voltage equation. The tutorial includes practical examples, such as calculating the voltage across a wire and the wings of an airplane moving through Earth's magnetic field. The video concludes with a call to action for viewers to engage with the content.
