Energy conversion means saving energy.

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.
