Magnetic Effects Of Current Question 21
Question: A vertical straight conductor carries a current vertically upwards. A point P lies to the east of it at a small distance and another point Q lies to the west at the same distance. The magnetic field at P is [MNR 1986; DPMT 2004]
Options:
A) Greater than at Q
B) Same as at Q
C) Less than at Q
D) Greater or less than at Q depending upon the strength of the current
Show Answer
Answer:
Correct Answer: B
Solution:
If distance is same field will be same $ ( \because ,B=\frac{{\mu_{0}}}{4\pi }\cdot \frac{2i}{r} ) $
