To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...
Setting up your space as a host for pop-ups is a great way to fill an otherwise empty location with an interesting and unique concept. It’s perfect not only for landlords who envision a permanent place for a rotation of temporary activations but also for those who want to gain revenue ...
The rotor here is like the nail in our previous example, and the stator is like the horseshoe magnet. When DC power is sent through the rotor, it creates a temporary electromagnetic field that interacts with the permanent magnetic field of the stator. The commutator's job is to keep the ...
Turn the magnet over and try again to see what happens. What Happened: The armature is a temporary magnet, getting its force from the electrical current in the battery. The neodymium magnet is permanent, meaning that it will always have two poles, and cannot lose its force. These two ...
On the other hand, the north end of one magnet will repel the north end of the other (and similarly, south will repel south). An electromagnet is the same way, except it is temporary — the magnetic field only exists when the electric current flows. You can determine the strength of a...
For a temporary solution, set up some fans to blow intruders away. Grab some large standing fans and set them up so that the air blows over your deck and away from your home. Wasps aren’t the smartest, and if a stiff breeze blows them away from your deck, they’re usually just con...
Put the coil near to a big, permanent magnet and the temporary magnetic field the coil produces will either attract or repel the magnetic field from the permanent magnet. If the coil is free to move, it will do so—either toward or away from the permanent magnet. In an electric motor, ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
No matter what you choose, think about these three concepts to make interesting, layered beats. Tension: Found in juxtaposition, tension is what pulls the song forward. It is the difference between the intense moment before a "drop" in dubstep and the cathartic, slower boom after the drop ...
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
