How Electric Guitars Work

17/2/2021If you have read How Electromagnets Work, then you know that coils and magnets can turn electrical energy into motion. In the same way, they can turn motion into electrical energy. In the case of an electric guitar, the vibrating steel strings produce a corresponding vibration in the magnet's magnetic field and therefore a vibrating current in the coil.

20/2/2021Magnetic fields may be represented mathematically by quantities called vectors that have direction as well as magnitude. Two different vectors are in use to represent a magnetic field: one called magnetic flux density, or magnetic induction, is symbolized by B; the other, called the magnetic field strength, or magnetic field intensity, is symbolized by H.

How to Avoid Black Fly Bites

In much of North America, the problem of black flies is largely unknown, but in areas where black flies are bad, they're really bad. These biting insects are a real nuisance and, in many cases, potentially deadly because of their sheer numbers. In the most severely affected areas, protecting yourself against black flies can make or break your plans to spend time outdoors.

How does gravity work?

So the farther apart the particles are, and/or the less massive the particles, the less the gravitational force. The standard formula for the law of gravitation goes [source: UT]: Gravitational force = (G * m1 * m2) / (d2) Gravitational force = (G * m1 * m2) / (d 2) where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force,

Q A: How do magnets work?

Magnets attract other magnets (as you can see), and also attract some kinds of metal like many kinds of steel. If you touch your magnetic needle with a steel screwdriver it will stick. However, stainless steel is not a very good magnetic material, so if you touch your magnetic needle with something made of stainless steel it will probably not stick (try it).

Looking for a magnet that can attract gold

If such magnets could attract gold, they would likely be used by prospectors and large scale miners to collect gold from dirt. The most efficient way that most people use is panning or a similar concept, where water is used to push lighter material to one side, while the heavier (gold) material gathers at a lower point in the vesicle.
