If this is the complete statement of the homework problem then you could start by listing the things that you don't know. For example,
1) What is the shape or geometry of the capacitor?
2) What is the the current flow into the capacitor?
3) Is the capacitor currently inside an active MRI?

The request is to write the law B(r), using the current i that flows in the circuit (the capacitor is in a activate circuit). The capacitor has two round parallel plates. We have no numerical values.

Welcome to the PF. 
For example:
I'm pretty sure that there are some words missing in the translation and/or there is a figure of the circuit that goes along with the question.Fabio97 said:
For example:
- What is the law describing the magnetic field as a function of the circuit wire loop radius connected to a capacitor?
- What is the law describing the magnetic field as a function of the AC current i(t) flowing through a capacitor as a function of the radius of the capacitor?
- (other tries?)
