Explanation of what the Hall effect is, how exactly the Hall voltage is generated and how you can calculate it and the Hall constant.

Learn what the Hall effect is, how the Hall voltage is generated in a current-carrying bar in a magnetic field, and how this voltage is derived.

Learn what inductive reactance is and how to determine it for a coil (inductor) in an AC circuit.

Learn what inductive reactance is and how to determine it for a coil in an AC circuit.

In this short video you will learn what the reactance of a capacitor is and how to calculate it.

Learn what capacitive reactance is and how to determine it for a capacitor in an AC circuit. We also make a simple example!

In this physics video, you will learn how a mass spectrometer is constructed and how you can use it to determine the mass of charged particles.

Here you will learn what voltage is, how it is generated by charge separation, how a voltage source can be created, and what voltage has to do with current.

Derivation of the formulas for the Lorentz force on a current-carrying wire in the magnetic field or Lorentz force between two current-carrying wires.
