Physics · Class 12 · CBSE — Moving Charges and Magnetism
Two insulated concentric coils, each of radius R, placed at right angles to each other, carry currents I and \(\sqrt{3}\) I respectively. The magnitude of the net magnetic field at their common centre will be
- \(\frac{\mu_{0} I}{R}\)
- \(\frac{\mu_{{o}} {I}}{2 {R}}\)
- \(\frac{\mu_{{o}} {I}}{4 {R}}\)
- \(\frac{2 \mu_{{o}} {I}}{{R}}\)
Answer
(A) _ 0 I R
