Does the magnetic field around an inductor propagate indefinitely or does it collapse on itself. For example: if you were to turn the current on and off the magnetic field would it simply propagate outward weakening as the distance grew until it became nothing but elementary particles or would it collapse back on the inductor? In other words, could an inductor replicate a traveling magnetic field.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
