What are free electrons? - Conductors and insulators - CCEA - GCSE

WebWhen electricity flows, the electrons are considered "free" only because there are more electrons than there should be, and because the transition metals, such as iron, copper, lead, zinc, aluminum, gold etc. are willing to transiently accept and give up electrons from the d -orbitals of their valence shell. WebSep 12, 2024 · The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip. This leaves an excess of positive charge at the top edge of the strip, resulting in an electric field E directed from top to bottom. the organized student by donna goldberg
