Practice will be decided by your application's requirements. You want a magnetic field, but have not specified the "spatial volume" or...

You are sweeping Pin (whatever that is) from -20v to +20v in steps of 1v, which is 41 trace sweeps. To perform a logarithmic sweep you...

I assumed it was when your bias control circuit began to regulate, or the output voltage saturated. Maybe change the step parameters to...

There is a tradeoff, is it easier to synchronise the internal 1'st LO synthesisers of two SDRs, or to build two RF front-ends with 1'st...

Modified the signal input, so only one parameter is needed. I have given you a .STEP command. For vin = 1.0v to 3.5v step 0.5v...

It is difficult to do those simulated tests because you have two trapezoidal inputs, with feedback from the amplifier output to the...

Old ice is not amorphous, it is a crystalline solid, like a rock made from crystals of H2O. Glaciers flow, and skates glide, because...

Commercial jets have a cylindrical shape fuselage, between a parabolic nose and a conical or wedge shaped tail. The cylinder maximises...

All stagnant space connected to the inlet would be subjected to that internal pressure. A pinhole, on the front of a hypersonic...

The pressure will fall from the inlet to the outlet as the radiator will partly obstruct the airflow, while the heated air will increase...

I disagree. Aircraft have a sharp edge convergence at the rear to reduce wake and drag. They also have a blunt or spherical nose, where...

As the body displaces fluid, the fluid surface will rise, so the reference from which d is measured is changing.

I would expect the efficiency of both cooling and thrust development to be proportional to the temperature difference between the inlet...

Because warmer ice flows, and bubbles of historical air in the ice can move.

At 500 kph, the ram air pressure will be about 1.7 psi. The rocket envelope will need to handle that internal pressure, along the sides...
