A current `I` flows in a long thin walled cylinder of radius `R`. What pressure do the walls of the cylinder experience ?

A current I flows along a thin-walled, long, half-cylinder of radius R(figure) Find the magnetic induction at a point on the axis of the cylinder

A currents I flows along a long, thin-walled tube of radius R with a long longitudinal slit of width h. Find the induction of the magnetic field at a distance r lt R from the axis of the tube under the condition h lt lt R .

The figure shows a long coaxial cable in which a current I flows down through the inner cylinder of radius a and the same current flows back up through the outer cylinder of radius 2a. The cylinders are insulated from each other and the current is uniformly distributed over the area of the cross-section in each cylinder. The strength of the magnetic field at a distance 3a//2 from the axis of the cable is
