The typical area of a commercial airplane's passenger window is 80.0 in2 . at an altitude of 3.00 × 104 ft above the sea level, the atmospheric pressure is 0.350 atm. determine the net force on the passenger window during flight at that altitude for both the english engineering (ee) and si unit systems. use appropriate units and unit conversions in all steps of your calculations.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
