I want magnetic force on one end of the magnetic bar only, but not on the other end. Will it work if I attach a big piece of iron on that end of magnetic bar which I do not want to have magnetic force? Imagine that big piece of iron will absorb all the magnetic flux from that end which i want...

Hello, When is it OK to connect the shield wire of a loadcell to the 0V rail vs chassis ground? I have seen it connected to the 0V rail but other sources seem to indicate that it should be connected to chassis ground. Any thoughts/advise? Thanks

Hi, is it possible in (theory) to somehow combine lots of atoms, protons ect and make a shield that pushes gravity outwards in every direction so the aircraft or whatever was the weightless? if that were possible, would we be able to travel near the speed of light or even 1/4 the speed of light...

why is it not possible to shield gravitational forces although we can shield electric forces?? is it so because gravitational field arises only due to the distortion of electrons of a body by a massive body? how this concept can help me to understand or resolve the problem? pleeeeeeeeeeeeeese...

Hello, I have seen some very good analysis on this website. Therefore, I would like to get some comments on my idea. I was thinking how practical is to develop a sheild by rapid and powerful shooting of numerous Iron blades (with diameter and length slightly bigger than a bullet) over a...

I am wondering if there is a way to put shielding on a simple magnetic bar mad out of neodymium so that the magnetic field is not emanating from all over but just at the ends. I/E a magnet shaped like a can of soda. Putting some type of Shielding on what would be the label section so that the...

Hi, What is the correct way to connect the bare shield wire of cat 5 STP to a shielded RJ45 plug? Thanks
