You are standing 1.9m from a 130W- lightbulb.
a. If the pupil of your eye is a circle 5.0mm in diameter, how much energy enters your eye per second? (Assume that 5.0% of the lightbulb's power is converted to light.).
b. Repeat part A for the case of a 1.0mm--diameter laser beam with a power of 0.50.
The magnetic field between the poles of an electromagnet is 2.17 T. A coil of wire is placed in this region so that the field is parallel to the axis of the coil. How many turns are there in the coil
