Physics Question on Magnetic Field Due To A Current Element, Biot-Savart Law
A (+)vely charged particle is placed near an infinitely long straight conductor where there is zero gravity. Then
A
the charged particle will not move
B
it will move parallel to the straight conductor
C
it will move perpendicular to the straight conductor
D
it will move with constant acceleration
Answer
the charged particle will not move
Explanation
Solution
As the charged particle is at rest, no force will act on it due to the magnetic field produced by the conductor at the site of the charge. Hence, it will remain at rest.
