Magnetic Effects Of Current Question 8
A circular loop carrying current lies in XY plane with its center at origin having a magnetic flux in negative Z-axis. Reason : Magnetic flux direction depends on the direction of current in the conductor.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason are both false.
E) If assertion is false but reason is true.

Answer:
Correct Answer: C
Solution:
The direction of magnetic field due to current carrying conductor can be found by applying right hand thumb rule or right hand grip rule. When electric current is passed through a circular conductor, the magnetic field lines near the center of the conductor are almost concentric circles. Magnetic flux direction is determined only by the direction of current.
