Calculate the inductance of a coil as an educational exercise or if you expect someday to build a radio from spare parts. The coils you buy will have the henrys (measure of inductance) clearly marked. Knowing the formula will help you understand the behavior of coils, and there is no bet...
Magnetizng the Rod Determine the poles on your magnet. On most magnets, this should be shown with an N on one end and an S on the other. Decide which pole you want to use to create your magnet. This is purely preference and will not affect the strength of your magnet. Position the ...
to this head are quite thin. i doubt they could take a current of more than 1 mamp. the platter is about 0.1 mm from the head. with these crazy assumptions, i can calculate the magnetic field from this small electromagnet. if you have a small loop of wire with current, the magnetic ...
Now, I will finish by answering some other questions. It is known that a magnet's strength can be increased or induced by an electric field. This is called an electromagnet. My critic will ask how my situation above could be increased. Haven't I just turned off the spin of the photons...
It's easy to calculate how much difference an amplifier makes: it's the ratio of the output signal to the input signal, a measurement called the gain of an amplifier (or sometimes the gain factor or amplification factor). So an amplifier that doubles the size of the original signal has ...
How to Calculate Torsion Constant How to Calculate the Debye Length Multiply the torque applied to the beam by the length of the beam. Ensure that the length of the beam is in meters. Divide the value from Step One by the angle of twist of the beam. Ensure that the angle is in ...
This requires a powerful electromagnet, which can be used to adjust the strength of the permanent magnet in the speedometer until the needle matches the input from the rotating drive cable. Speedometer Accuracy No speedometer can be 100 percent accurate. In fact, most manufacturers build speedometer...
these types of bearings support moving loads without physical contact through magnetic levitation. Valued for their frictionless operation and ability to run without lubrication, magnetic bearings are a low-maintenance alternative to mechanical bearings with a longer lifespan. Learn how to calculate design...
