The easiest way to create a powerful magnetic field is by creating a powerful electromagnet. Electromagnets are used for everything from powering tiny electronic switches (called relays) to lifting huge pieces of scrap metal. The density of the winding, the amount of current flowing through the m...

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...
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...
How to make a magnetic field stronger. Why is the magnetic force perpendicular to the magnetic field? How can a permanent magnet lose its magnetism? How to draw magnetic field lines around a bar magnet? How does heating a bar magnet change its magnetic field?
Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...
Directions to see the effects of Magnetic Field Step-1: In the first step, arrange a piece of paper on a flat surface and place a bar magnet over it. Step-2: Gently, sprinkle the iron filings around the bar magnet and make sure they spread all over the paper as a second step. Step...
