AP EAMCET · PHYSICS · Magnetic Effects of Current
A long straight wire carrying electric current ' \(i\) is bent at its mid-point to form an angle of \(45^{\circ}\) as shown in the figure. Magnetic field at a point \(P\) at a distance \(d\) from the point \(Q\) of bending is
- A \(\frac{\mu_0 i}{4 \pi d}[\sqrt{2}-1]\)
- B \(\frac{\mu_0 i}{2 \pi d}[\sqrt{2}-1]\)
- C \(\frac{\mu_0 i}{4 \pi d}\)
- D \(\frac{\mu_0 i}{2 \pi d}\)
Answer & Solution
Correct Answer
(A) \(\frac{\mu_0 i}{4 \pi d}[\sqrt{2}-1]\)
Step-by-step Solution
Detailed explanation
Magnetic field at a point from a current carrying conductor making angle \(\theta_1\) and \(\theta_2\) with the ends of wire is given using Bio-Savart's law as…
