A long, straight, cylindrical conductor contains a cylindrical cavity whose axis is displaced by _a_ from the axis of the conductor, as shown in the accompanying figure. The current density in the conductor is given by \mathbf{\overset{\rightarrow}{J}} = J_{0}\mathbf{\hat{k}}, where J_{0} is a constant and \mathbf{\hat{k}} is along the axis of the conductor. Calculate the magnetic field at an arbitrary point P in the cavity by superimposing the field of a solid cylindrical conductor with radius R_{1} and current density \mathbf{\overset{\rightarrow}{J}} onto the field of a solid cylindrical conductor with radius R_{2} and current density \text{−}\mathbf{\overset{\rightarrow}{J}}. Then use the fact that the appropriate azimuthal unit vectors can be expressed as {\hat{\theta}}_{1} = \hat{k}\ \times \ {\hat{r}}_{1} and {\hat{\theta}}_{2} = \hat{k}\ \times \ {\hat{r}}_{2} to show that everywhere inside the cavity the magnetic field is given by the constant \mathbf{\overset{\rightarrow}{B}} = \frac{1}{2}\mu_{0}J_{0}\mathbf{k}\ \times \ \mathbf{a}, where \mathbf{a} = \mathbf{r}_{1} - \mathbf{r}_{2} and \mathbf{r}_{1} = r_{1}{\hat{r}}_{1} is the position of _P_ relative to the center of the conductor and \mathbf{r}_{2} = r_{2}{\hat{r}}_{2} is the position of _P_ relative to the center of the cavity.
