Regarding a slight modification to the electric generator configuration

AI Thread Summary
Rotating a magnet and a coil in opposite directions can increase the voltage generated compared to a stationary coil with a moving magnet at the same RPM. The key factor is the relative speed between the magnet and coil, which enhances the magnetic field interaction. This configuration could potentially lead to a stronger induced voltage due to increased relative motion. However, the overall voltage output will also depend on additional factors like magnet strength and coil turns. Further experimentation is necessary to fully understand the impact of this modification on generator performance.

suppose a magnet and a coil are made to rotate in the opposite direction relative to each other, will this result in a higher voltage at a rpm as against the stationary coil and moving magnet configuration at the same rpm ?
i've also attached a figure to illustrate the configuration.

It's only the relative speed that determines the voltage generated.
 
exactly, which will be increased if they rotate in the oppposite direction.
 
This is an interesting concept and it could potentially result in a higher voltage output at the same rpm compared to the stationary coil and moving magnet configuration. This is because the relative motion between the magnet and coil would be increased, leading to a stronger magnetic field and inducing a higher voltage in the coil. However, other factors such as the strength of the magnet and the number of turns in the coil would also play a role in determining the voltage output. Further experimentation and analysis would be needed to determine the exact effects of this modification on the electric generator's performance.
 
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'
I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
