Biot-Savart's law indicates that the moving electrons (velocity v) produce a magnetic field 
such that:
A
is perpendicular of velocity
B
is parallel to velocity
C
It obeys inverse cube law
D
It is along the line joining the electron and point of observation
Text Solution
Verified by ExpertsThe correct answer is:
A
In Biot-Savart's law, magnetic field 
and 
due to flow of electron is in opposite direction of v and by direction of cross product of two vectors 
.
