We're told that we have a long, straight wire carrying a current of two amperes placed along the access of a cylinder which has a radius of 20.5 meters and a length of three meters. And it wants us to determine the total magnetic flux through the cylinder. Okay, well, from the right hand thumb rule, we can say that the direction the direction of the current along the thumb and the magnetic field is upwards. I'II tangent to the surface of the cylinder. So that night, no magnetic field lines penetrate the cylindrical surface. So therefore, since the magnetic flux is five be equal to be magnetic field times the area times the co sign of the angle Fada. But from the right hand rule, we determined that data here is equal to 90 degrees and the coastline of 90 degrees is equal to zero. Therefore, the magnetic flux is gonna be equal to zero
