Magnetic Effects Of Current Question 164
Question: A straight wire carrying a current $ i_{1},amp $ runs along the axis of a circular current $ i_{2},amp $ . Then the force of interaction between the two current carrying conductors is
Options:
A) $ \infty $
B) Zero
C) $ \frac{{\mu_{0}}}{4\pi }\frac{2i_{1}i_{2}}{r}N/m $
D) $ \frac{2i_{1}i_{2}}{r}N/m $
Show Answer
Answer:
Correct Answer: B
Solution:
As shown in the following figure straight wire is placed parallel to the magnetic field produced by circular current. Hence force on wire F = 0
