Two similar coils which are separated by \(2 \mathrm{~m}\) having radius of \(1 \mathrm{~m}\) and number of turns 80 have a common axis. Calculate the strength of magnetic field in microtesla at a point midway between them on their common axis when a current is \(0.2\)
- A \mathrm{~A}\(.\)0.04 \sqrt{2}$
- B \(1.6\)
- C \(\frac{0.04}{\sqrt{2}}\)
- D \(\frac{\sqrt{2}}{0.04}\)
Answer & Solution
Correct Answer
(D) \(\frac{\sqrt{2}}{0.04}\)
Step-by-step Solution
Detailed explanation
The given situation is shown below, Net magnetic field, \(\mathbf{B}_{\text {net }}=\mathbf{B}_1+\mathbf{B}_2\) Since both the magnetic fields are in same directions. So, the magnitude of net magnetic field can be calculated by algebric addition of magnitudes of \(\mathbf{B}_1\)…
