thank you very much.

here are the question below. please answer all the question, not just answer 1 question.

2.) 0.75 A of current flows in a copper tube of inner radius 2.0 cm and outer radius 2.54 cm. Find the strength of its magnetic field as a function of radius, from r = 0 to r = infinity.

3.) A wire is placed on the x-axis and current flows in the positive x direction. Another wire is placed on top of it (higher z-component) that is parallel to it but the current flow in the negative x-direction. In which direction will the first wire be pushed, if any? In which direction (if any) will it want to rotate?

4.) A current loop is placed on the x-y plane centered at the origin and current flows in the clockwise direction as viewed from above (from higher z-value). We place a wire on the x-axis that has current flowing in the positive x-direction. In what direction will the wire be pushed?
