Guitar Pickup Physics: Electrical Engineering Help
Q: I'm doing a computer simulation project where I am trying to accurately reproduce the sound of an electric guitar with computer software. To do that I need to know a little more about the physics of the guitar pickup. I know that is consists of a fixed magnet around which is a coil of wire. The electric string is simply steel which is magnetized. When the magnetized string moves through the field of the pickup's fixed magnet *something happens with electromagnetic flux*, and by inductance a current is produced in the coil, which goes to the amplifier and makes sound. The something is where I get lost. A few questions: 1. the string vibrates in a plane perpendicular to the fixed magnet. Faraday's law of inductance seems not to hold in this case. What equations should I use to calculate the induced current? 2. how is the string magnetized? 3. after the current is produced in the wire, what does the amp do with it? Both ends of the wire are connected to the amp. How does the amp work? 4. how do filters and pedals work? 5. how many times is the wire coiled around the fixed pickup magnet? Like I said, I am trying to make the simulator pretty damn accurate. I have the string in motion already, but I need more help with the pickup and amplifier physics.
A: 1. e = mc2 2. You take it and rub it up against one of those magnets with the local
