Menentukan Arah Gaya Lorentz

Summary

In this practical session, students explore the Lorentz force, a fundamental concept in electromagnetic theory. The experiment involves using aluminum foil, a power supply, and a magnet to observe how the foil reacts in an electric field. Safety precautions, such as wearing laboratory coats and gloves, are emphasized. Participants connect aluminum foil to a power source and place a magnet above it, noting changes in the foil's behavior. The experiment also examines the effects of reversing the magnet's position, prompting students to analyze their observations and identify patterns in the foil's reactions to the magnetic field.
