A long straight current carrying conductor has current directed from bottom to top when held vertically.what will be the direction of magnetic field lines when observed from below the conductor?
a.clockwise
b.anticlockwise
c.vertically upward
d.vertically downward
Answers
Answer:
Answer is C.
Explanation:
The direction of the magnetic field can be determined by the thumb rule.
When an electric current passes through a straight wire, the thumb points in the direction of the conventional current (from positive to negative), and the fingers point in the direction of the magnetic lines of flux.
In this case, a straight wire is held vertically and the current passes through this wire in the downward direction. Therefore, the magnetic lines of force in the clockwise direction.
Answer:
b.anticlockwise
Explanation:
The direction of the magnetic field can be determined by the thumb rule.
In your case, a straight wire is held vertically and the current passes through this wire in the upward direction. and hence, when you place your hand in the respective position and observe it from bottom it will be anticlockwise direction..
