When eddy currents are produced in the conductor, electrons in that conductor _____

When electrons drift in a metal from lower to higher potential, does it mean that all the 'free' electrons of the metal are moving in the same direction ?

The ratio of number density of free electron and hole in p-type semiconductor is …….

A very long straight wire carries a current of 5 A. An electron moves with a velocity of 10^(6)ms^(-1) remaining parallel to the wire at a distance of 10 cm from wire in a direction opposite to that of electric current. Find the force on this electron. (Here the mass of electron is taken as constant) (e=-1.6xx10^(-19)C,mu_(0)=4pixx10^(-7)SI)
