Electromagnets are created by running an electrical current through a conductive metal. An electrical current causes the rapid movement of electrons, which creates a magnetic field. Electromagnetic fields can be created by running an electrical current through any metal, including non-ferrous conductive ...
Before we tackle why electricity and magnetism are related, first we must understand what electricity and magnetism are when regarded separately (though that is truly a difficult thing to do because they are so closely related). Electricity involves the flow of electrons. Magnetism is the phenomenon...

Why are electromagnets used? Why is hexane known as a hydrocarbon? Why is the promoters on the noncoding strand? Why is ethanol used in perfumes? Why is sodium bicarbonate used in esterification? Why is HCL an acid? How does a nanodrop spectrophotometer work? Why do while benzene fluoresces...
However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as lenses, as do all electron microscopes. The electromagnets bend the electron beam to magnify and focus an image onto a viewing screen or photographic film. [#paragraph7]Electron microscopes have ...
How does a wig wag work? The Magnetic Flagman wigwag waves itstarget using large, black electromagnets pulling against an iron armature. Sliding contacts switch the current from one magnet to the other. Each Magnetic Flagman includes a builder's plate (bottom center) detailing patent dates and...
I won't be able to start my project until my birthday, when I can buy the materials, but I have some questions. I don't want to do this unless I can show that the power generated is somewhat close to the input power. I mean, it won't make sense if the output is 70% of the...
"For steel we used electromagnets to pick up the parts," Blosser says. "That obviously wouldn't work with aluminum because it's nonferrous, so we had to go to the vacuum system." I walk around to the output end of the press, where F-150 fenders are dropping onto the conveyor belt ...
b) Electromagnets are weaker than permanent magnets. c) A magnet always has a north pole and may or may not also have a south pole. d) A permanent magnet can be turned off.Explore our homework questions and answers library Search Browse Browse by subject Ask a Homework Question Tu...
Why are electromagnets used? Why do you analyze ELISA samples in triplicate? Why do seismometer oscillate back and forth? Why does a protoplanetary disk flatten? Why do scientists need a standard system of measurement? How does ultrasound imaging work? For paper chromatography, why was pencil used...
