| ### Statement | |||
| − | $9.3.19.$ | ||
| + | $9.3.19.$ The current distribution in two mutually perpendicular plates of thickness $h$ is shown in the figure. | ||
| + | There is no current in the area where the plates intersect. Draw a graph of the magnetic field induction | ||
| + | as a function of $x$. | ||
| + | |||
| ### Solution | |||
| In Problem 9.3.17, a formula was obtained for the induction inside the plate. On its axis, it is zero and increases linearly with distance from the plate: $$B=\mu_0 j x$$ | |||
| This means that, moving along the x-axis, only the transverse plate makes a contribution, and when we leave it, the induction becomes constant and equal to $$B_{max}=\frac{\mu_0 j h}{2}$$ | |||
