Steradian
The accepted unit for luminous intensity I is the candela (cd) or lumen per steradian; the imperial unit used prior to this was the candlepower. Figure 2.14.1. Illumination effect of a point source of light. The illuminance, denoted by E, is the luminous flux falling on a surface. The unit of illuminance is the lumen per square metre, such that:ste· ra· di· an sti-ˈrād-ē-ən. : a unit of measure of solid angles that is expressed as the solid angle subtended at the center of the sphere by a portion of the surface whose area is equal to the square of the radius of the sphere.

To take a step back though, you get roughly 1.5kW/m^2 irradiance from the sun.The radian, denoted by the symbol rad, is the unit of angle in the International System of Units (SI) and is the standard unit of angular measure used in many areas of mathematics. It is defined such that one radian is the angle subtended at the centre of a circle by an arc that is equal in length to the radius.

If the system had no hard or soft iron sources and you rotated the magnetometer all around in four pi-steradian directions, then the magnetic field vector would trace out a perfect sphere with the radius being the magnitude of the field. Now, a hard iron source would offset the sphere and a soft iron source would distort it into some ellipsoid.A steradian is (180/π) 2 square degrees or about 3282.8 square degrees. What is steradian in physics class 11? Steradian is a unit of measurement for the solid angles. Steradian is the angle subtended, at the center of a sphere, by a surface whose magnitude of area is equal to square of the radius of the sphere.
