(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The question actually asks for the equation for the magnetic field for the rotating disc; but all I'm after is the direction of the magnetic field.

2. Relevant equations

None were given; but I've been using:

[tex] \nabla \times \vec{E} = -\frac{\partial \vec{B}}{\partial t}[/tex]

3. The attempt at a solution

When I use the above equation I get two components to the magnetic field: [tex]\hat{r}[/tex] and [tex]\hat{\theta}[/tex]. That doesn't really make a lot of sense to me. What am I missing?
