Magnetic Fields
... • Note big difference with grav force and electrical force: - magnetic force does not act along the line joining the interacting objects; rather it is perpendicular to both field and the charge’s path. • This deflective action is used in (old style) TV’s • Cosmic rays: charged particles streaming in ...

The Drude Model and DC Conductivity
... Warning: The "oxidation state" of an atom in a molecule gives the number of valence electrons it has gained or lost through bonding. In contrast to the valency number, the oxidation state can be positive or negative. Sometimes called valence in physics. ...

Contributions of Maxwell to Electromagnetism
... the directive property of magnets as early as the lIth century. These magnets were natural' ones and were called loadstone (Fe30 4 ). Pierre de Maricourt (1269) discovered that a piece of loadstone in the globular form had a peculiar property. He brought a small magnetic needle and marked the line a ...
