Hello Student,

Please find the answer to your question

True. A copper wire consists of billions and billions of free electrons. When the wire is at rest, the average velocity of electrons. When the wire is at rest, the average velocity of each electrons is zero. But when the wire is in motion.

NOTE : A charged particle moving in a magnetic field. experiences a force given by $\underset{F}{\rightarrow}$ = q ( $\underset{v}{\rightarrow}$ x $\underset{B}{\rightarrow}$ ) Here also each electron experiences and therefore, electrons will move towards one end creating an emf between the two ends of a straight copper wire.

Thanks

AB is a current carrying conductor in the plane of the paper as shown in the figure below. (i) What is the direction of the magnetic field produced by it at point ‘X’? Write the statement of the rule used to find the direction of field lines. (ii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed? (iii) Point ‘X’ is at a distance r1 and point ‘Y’ is at a distance r2 (r1
