a. In a straight stationary conductor, the electron velocity is −βc, and the
proton velocity is zero. The electron and ion space charge densities are ±ρ.
How will the density of electrons and ions change when a conductor moves at
the speed βc?
b. How many times will the magnetic field induction in a moving conductor
change?
→−
c. How are the magnetic field induction in a moving conductor B related to
→−
the electric voltage E ?
→− →−
