Vedclass · Answer

(A) $1$. The magnetic field produced by a moving charge is given by the Biot-Savart law,where the direction of the current $I$ is defined as the direction of flow of positive charge.$2$. $A$ negative charge moving towards the observer is equivalent to a positive current moving away from the observer.$3$. According to the Right-Hand Thumb Rule,if you point your right thumb in the direction of the conventional current (away from the observer),your fingers curl in the direction of the magnetic field lines.$4$. From the perspective of the observer,looking at the charge moving towards them,the conventional current is moving away. Therefore,the magnetic field lines will appear to circulate in a clockwise direction.

$A$ negative charge is moving towards the observer. What will be the direction of the magnetic field produced by it,as seen by the observer?
