Electromagnetic induction question

Very long (theoretically infinitely long) cylinder of antiferromagnetic material with radius a is uniformly charged by its volume with charge of volume density ρ. The cross-section of a cylinder is shown on an image. Cylinder rotates around its axis with constant angular velocity ω. Electromagnetic permeability is equal to 0 (permeability of vacuum). Determine the vector of electromagnetic induction at point A that is located on an arbitrary distance R < a from the axis of a cylinder. Assume that the distribution of charge doesn't change with rotation of a cylinder. Indicate all vectors and used reference directions.

Question: How to set up equations and vectors/reference directions?
