At point A let be the z-axis points out of the page then then angular momentum is given by
L =mvr = rXP= rPsintheta =10kgm/s*4m = -40 kg*m2/s here theta =90 they are perpendicular
Now from the RHR we get the -Z direction

A circular loop of wire, centered at the origin, lies in the xy plane. The loop has a radius of 10.0cm. A cylindrical magnet (radius 0.5 cm and length-5 cm) starts out at rest with its primary axis along the z-axis. The bottom tip of the magnet is a north-pole and is situated at z 8 cm. The magnet is dropped straight down so that it falls north- pole down and it goes straight through the center of the loop....
