This lab activity lets you visualize electric fields, which are invisible forces created by electric charges. By suspending small particles like seeds or fibers in a liquid medium and applying an electric field, these particles align themselves along the field lines, making the field visible. This provides a tangible way to understand the direction and strength of electric fields around different charge configurations. The density of the aligned particles indicates the strength of the electric field at that point.
The setup typically involves placing two electrodes with opposite charges in a dish filled with a non-conductive liquid (like mineral oil) containing the suspended particles. When a voltage is applied, the particles become polarized and align with the electric field, creating a visual representation of the field lines.
