The direction determines if they will be attracted or repelled. The strength determines if the force is strong enough to actually move the magnet one way or another. So the magnetic field can create a force that can pull two magnets together or push them apart. ...
trap, electrocute or otherwise dispatch disease-carrying mosquitoes. Many of these devices or chemical repellents only offer marginal protection, or no substantial protection at all. One promising type of mosquito trap, however, is called a Mosquito Magnetreg;, and it works primarily by imitating o...
When two wires have an electric current running through them, there will be a magnetic attraction between them if the currents run in the same direction. The wires will repel each other if their currents are in opposite directions. Earth is a magnet that is produced by electric currents in ...
So far we’ve got that current flowing in the same direction down two wires makes those wires attract, and current flowing in opposite directions makes them repel. To get the magnets of your childhood (some of our childhoods) all you have to do is turn that wire into a loop. A loop o...
On the other hand, the north end of one magnet will repel the north end of the other (and south will repel south). Inside an electric motor, these attracting and repelling forces create rotational motion. Contents Inside an Electric Motor How a DC Motor Works Toy Motor Rotor, ...
Magnets always exist asdipoles. In other words, you can't cut a magnet in half to separate north and south. Cutting a magnet makes two smaller magnets, which each have north and south poles. The north pole of a magnet is attracted to Earth's north magnetic pole, while the south pole ...
The striped coloring on sheepshead fish (Archosargus probatocephalus) makes them look like they broke out of some type of old-timey aquarium chain gang. But what's more bizarre than their striped patterns is what's inside their mouths: a top row of teeth that look positively human and a...
…For the first time in years, you feel content. All problems in your life have become irrelevant.The feeling of having her as a potential partner makes you feel complete. As if she was the missing piece to your life you’ve been searching for all along. ...
whereas electromagnetic movements (which depend on the flow of current through a wire to generate a magnetic field) are much lower in resistance. As we will see in greater detail to come, greater resistance (resulting in less current drawn from the circuit under test) makes for a better voltm...
Current flows to the output from the positive supply at the top when a negative input makes both of the p-channel MOSFETs in series at the top conduct; current flows from the output into the ground at the bottom when a positive input makes either of the n-channel MOSFETs in parallel at...
