It says on the pack of magnetite powder: 'Particle size: 95% < 170 mesh (~53µ)'. We are going 'dip' the tip of the object, having area pi*(0.2mm)^2, into this magnetic powder.

Hi I am designing a solenoid to interact with a magnetite-powder tip. I can't find specifications about the magnetite I am using, and properties seem to depend on factors I don't know. Could you give me a rough estimate (just order of magnitude is fine) of the force give a certain magnetic...

Hi all I'm from Bioengineering and unfortunately not too expert on the mechanical side. I'm making a device for which I need a mechanism to transform circular motion into oscillatory motion. I found the mechanism in the picture below...

Ok, I see, I thought that, if you just need to measure the output, you connect the ground of the picoscope to one of the two ouputs and then measure the other one. But I guess if you want to insert the circuit inside a bigger circuit you could not do that

Hi, I'm looking at a circuit of a classical instrumental amplifier having 3 opamps, 2 for buffer, with Rg to adjust the gain. The output from this buffer + gain circuit is then feed into a third opamp, in a circuit that is the 'basic' differential amplifier, but whose function now that Rg is...
