IB HL Physics Electric Field in a Moving Conductor
/A conductor moves in a magnetic field. Is the electric field in the conductor zero? A tutorial sheet follows.
- State Ohm's law in terms of electric field (E) and current density (J).
- A current flows through a stationary conductor that obeys Ohm's law. Is there an electric field inside the conductor? Outside of the conductor?
- A straight metal rod of length L is a perfect conductor (zero resistance). The rod moves at a constant velocity v along the x-axis through a uniform magnetic field B along the z-axis. The length of the rod is along the y-axis. Find the electric field in the rod in the (a) reference frame of the laboratory, (b) reference frame of the rod.
- In the previous question find the force acting on a charge q in the rod relative to the reference frame of the rod.
- In question 3 the rod has a constant non-zero resistance. Find the force on a charge q in the rod relative to the reference frame of the rod.
