For dry air at a temperature of 0∘C and at 1 atm of pressure, electric breakdown occurs when the air is subjected to an electric field with amplitude above about 3.00 MV/m. A high-power laser is shone up into Earth's atmosphere, and the laser's associated electric field ionizes the air and turns it into a conducting plasma. Assume the conditions of the air are such that an electric field of 3.00 MV/m causes the air to ionize. (a) What will be the intensity (in W/m2) of a laser beam that can produce a field of this magnitude? W/m2 (b) Assuming the laser is operating at this maximum intensity, what is the power (in W) delivered in a cylindrical beam with a diameter of d = 4.55 mm? W

Building an Adjustable Electromagnet. You and your team are tasked with designing a source to provide a uniform magnetic field for an experiment. The field inside a solenoid is uniform, provided that the length of the solenoid is much longer than its diameter. One useful characteristic of an electromagnet of this type is that the field inside can be adjusted anywhere between 0 T and some maximum value by controlling the current. In addition, the direction of the field, which is always pointed along the axis, can be reversed by reversing the current. The solenoid you are designing must be 3.60 cm in diameter and 25.0 cm long, and must generate a maximum magnetic field of magnitude B = 0.150 T. You intend to wind a cylinder of the given dimensions with wire that can safely pass a maximum current of 6.50 A. (a) How many windings should the solenoid have in order that the magnetic field at the center of the solenoid is 0.150 T when the current is 6.50 A? (b) What total length of wire is required? (c) What current should you pass through the coil to generate a smaller magnetic field of magnitude 3.50×10−2 T at its center, but directed antiparallel to the field generated in part (a)? Assume the current was positive in part (a). (a) Number Units (b) Number Units (c) Number Units
