    Custom mini push electromagnet & winding method

    I have a small but urgent electromagnet project in process however the actuator I need doesn't seem to be readily available although although it's not anything new, except for the custom size I need. Attached is a reference sketch. I ordered and received these 12mm OD buzzers 12mm WST-1212S...

    Small EM recommended specs info.

    We need to create a remote controlled electromagnet for the pick-up arm of the submarine we're working on. EMs are pretty simple devices but I need some help to clarify a couple issues. The EMs in mind will be 1" or less in size and won't use more than 24Volts but 12Volts or less is more likely...

    Parameters for small electromagnet

    I've been searching unsuccessfully for an electromagnet for my application and unless anyone can provide a source lead, I'll try to make one myself. I need some guidance for the parameters I need to say within so I don't waste time. It needs to be small, say no more than 1" long by 3/8" dia...

    Inorganic non-Newtonian fluids

    Hello, We're working on an application which we believe the behavior of a non-Newtonian fluid which becomes rigid when under stress. It needs to be inorganic so it won't spoil and as I understand it there are silicone polymers or oils which meet this criteria. Any other such fluid would be good...

    Determining specs for unmarked electric motors

    Hello, This is my first post here and I registered as per my specialty which is marine biology but it seems I'm the only such member. I do however, have an electrical question if it's allowed to cross forums. We're planning to develop and ocean going autonomous data and specimen collecting...
