Electric guitars are devices that generate sound from a set of pickups that convert string vibration into electrical signals for amplification. The sound starts out as vibrations the musician creates while playing. These vibrations are picked up by the pickups of the guitar. What are pickups? Pickups are permanent magnets wrapped around in a coil. Since the strings are made with a special material called ferromagnetic, they interact with the magnetic fields in the pickups and force electrons to move in the loop. Moving electrons can generate a signal that can be read by the amplifier.
Pickups work with a bar magnet which is rapped with turns of wire. We know that magnets with coil can transform electrical energy into motion. Also motion can be turn again into electrical energy. On a pickup, the vibration in the magnets is produces by the vibration that the ferromagnetic strings make. Then at the same time in the coil there is a vibrating current.
A knob on a guitar is considered a voltage divider. There is a relation between 2 resistors; all depends on the position. If the position is somehow there is no signal being resisted to ground, in that case there is full volume. The other situation is when it is fully turned all signals are shunted out to the ground so there is no volume.
Electric guitars function without any external power. The current is created by the vibrating strings that interact with the magnetic field and coils in the pickups since a force inside a magnetic field creates the current.

That is how we know the electric guitar as the "electric" guitar! A matter of fact, a guitar generates its own electricity! How does it do this? The pickups are generators of electricity. The strings are electro-conductive and vibrate around a wire and magnet coil, thus producing an alternating current.
The most common type of bass guitar is an electric bass guitar. Electric basses have solid bodies. An electric bass needs to plug into a amplifier to be heard over other instruments. A bass amplifier or amp, is pretty much a powered speaker. If you get an electric bass, you will also need a bass amp. An example of a electric bass would be the one I played in the WNE. The electric bass was the only bass that the school could provide for the band but we also felt it had the right sound for the job.
The Helmholtz resonance of a guitar is due to the air at the sound hole oscillating, driven by the springiness of the air inside the body. This is analysed quantitatively in Helmholtz Resonance.
The inner workings of the turntable may seem complex at first but after reading this paper it should become clear that, like all things, the record player works on basic principals of physics. In fact, the turntable is remarkable in that the basic physical principles behind it are quite simple. Some of these will be explored here. Please enjoy your visit.
When the gear of the dynamo is engaged, the generator wheel rolls against the chain wheel and the flywheel on the same shaft as the dynamo. The dynamo fit into the bracket welded near the back of the bike. The chain on the right is driven by the pedals, while an added chain on the left spins the motor. On the side that's driven by the pedals, a freewheel rotates the wheel when pedaling but allows it to keep spinning forward, without the chain moving. When pedaling backwards, on the left side of the wheel, a fixed cog spins in the direction of the chain whenever the wheel is turning. This motion produces electricity, and the greater the speed, the greater is the amount of electricity produced. The principle of energy c...

The electric guitar has greatly impacted how music was played in the past, the present, or the future. Players can be creative and achieve a great sound from the wide variety of guitars, pickups, pedals, or amps. Whatever type of music you enjoy, everyone should appreciate the importance of the electric guitar.

Guitars are very different instruments than they once were. They have had many changes in shape, sound, style, and how they are made. Starting out as tortoise shells with a stick and some strings, they have now developed into acoustics, spread from Europe to the rest of the world, and turned out to be the crazy shaped, cool designed electric guitars of today.
There are many and various parts of a bass guitar. They all have a specific function to the overall instrument. The electric bass can be divided into th...
A brushless DC motor has a permanent magnet or magnets for the armature. The external magnetic field comes from any number of electromagnets that are turned on and off at the correct times by a timing device.
To understand how this motor works, we must understand the relationship between electricity, and magnetism or simply put electromagnetism. Direct electric current in a simple description: There are two requirements for current flow. The first is a source of electrical potential energy or EMF (electro motive force,). The second is a conductor that provides a complete loop to carry the current. The reason a conductor will conduct is found on the atomic level. A conductive atom’s valance shell is not completely full electrons will flow from atom to atom because of this. When these electrons move from one atom to another that is electrical current (a brief description that is).
In some Greek experiments, objects attracted each other after rubbing. Other experiments produced objects that pushed away, or repelled, each other. The evidence showed that electric force made matter either attract or repel other matter.
Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
Humans these days take electricity for granted. We don’t truly understand what life was like without it. Most young adults will tell you their life does not depend on electricity, but they aren’t fooling anyone. They all know that their life depends on electricity; whether it’s television, their phone, Google, or the lights in their house. We need to stop taking those things for granted and give credit where credit is due. That is why I chose to write about the scientists who contributed to the discovery of electricity, which then helped modern scientists fuel the electricity phenomenons we now have today.
