How do drift velocity, current density, and electric field vary along the wire?
• Force on moving charge, charge density free electron density. – The full question is attached and comes in two parts, the first requires me to find the magnetic force acting on a point charge the second asks me to determine the charge density and current density o … • Magnetic Field, Drift Velocity and Hall Voltage. – The number density of free electrons in copper is 8.47 x 10 ^22 electrons per cubic centimeter. If a metal strip of copper 2 cm by 0.1 cm (thickness), magnetic field pointing up to top of paper, and … • Magnetic field due to currents flowing in a coaxial cable. – Please see the attachment. • Electrostatics: Surface charge density and electric field – Two part question involving a spherical cavity inside a shell and calculating: a) the surface charge density b) the electric field Problem is attached in word format. Diagram is included in … • Electrons & Charges – An electron is released from rest 2.0 cm from an infinite charged plane. It accelerates toward the plan
