charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field

Facing East provides snapshots into American Indian lives‚ actions‚ and thoughts. The first chapter‚ titled "Imaging a Distant World‚" relies heavily on an estimation drawing on actual known facts about initial encounters but filling in the blanks with imagined possible scenarios. The view east begins at Cahokia‚ the metropolis located across the Mississippi River from present-day St. Louis that flourished around 1100 A.D‚ and Richter employs its story to remind "us that the great changes occurring

One thing that uses magnetic fields is the electric motor‚ which is used in many household appliances‚ such as electric fans‚ microwave ovens‚ and other small appliances. In this instance the electric motor has an electric current‚ giving it also this magnetic field. An electric motor converts electricity into mechanical motion. Most electric motors work by electromagnetism‚ but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying
