AP EAMCET · PHYSICS · Magnetic Effects of Current
Two concentric loops \(A\) and \(B\) of same radius \(2 \pi \mathrm{~cm}\) are placed at right angles to each other. If the currents flowing through A and B are 3 A and 4 A respectively, then the net magnetic field at their common centre is
- A \(0.75 \times 10^{-5} \mathrm{~T}\)
- B \(0.75 \times 10^{-5} \mathrm{~T}\)
- C \(0.75 \times 10^{-5} \mathrm{~T}\)
- D \(0.75 \times 10^{-5} \mathrm{~T}\)
