Select a piece of iron for the magnetic core. A 6 to 8 inch long piece of iron, such as a large nail or spike, will create a powerful magnetic field, but you can use smaller or bigger rods if you prefer. Advertisement Step 2 Wrap the rod in magnetic wire (see Resources). Start a...

Hi all, I'm trying to model a magneto-mechanical interaction (my focus is on the structure) and I need to apply a uniform magnetic flux density in a cube of air (which is my domain) in the z direction. Is there a way to do it? I've tried different things (magnetic potential, ma...

As you know, we have seen that when current flows in a wire, a magnetic field is created around the wire. Current is simply a bunch of moving electrons, and moving electrons make a magnetic field. This is how electromagnets are made to work. This will be important to keep in mind as...
which made the needle behave like a magnet. You had to rub in one direction to get the atoms to all line up in the same manner. If you had rubbed back and forth, the atoms would not have lined up as well, and the magnetic field would probably not be as strong, if one was create...
NFC stands for Near Field Communication. It is a technology that allows wireless data transmission over short distances using radio waves. How do I turn off NFC on iPhone? You cannot explicitly turn off NFC on an iPhone. The feature is always on by default. The good news is that it consu...
How do plants help in recharging groundwater? Why does Earth have a magnetic field? How does wind shear affect wind turbines? What are the effects of Earth's magnetic field on ocean features? Why does magnetic field strength decrease with distance?
