Two thin, circular, coplanar wire loops share a common center. The inner loop has radius \(R\) and carries a counterclockwise current \(I\). The outer loop has radius \(2R\) and carries a clockwise current \(I_2\). Which of the following correctly pairs the required current \(I_2\) such that the net magnetic field at the center is zero, with the resulting magnitude of the net magnetic dipole moment \(\mu_{\text{net}}\)?
