guys im trying to do calculations for coils that i want to use...i dont know how to do faradays law..this is the information i have.... 2inch coils, 80 turns (4layers, 20turns each layer) average diameter is .75 inches. distance from magnet is .25inches. speed is 80turns in 1.123seconds (1 coil in 1.123 seconds) or .05615 per 4 turns magnet information (using 2 magnets...one on each side of coil) DCX8 # Dimensions: 3/4" dia. x 1 1/2" thick # Tolerances: ±0.002" x ±0.002" # Material: NdFeB, Grade N42 # Plating/Coating: Ni-Cu-Ni (Nickel) # Magnetization Direction: Axial (Poles on Flat Ends) # Weight: 2.87 oz. (81.5 g) # Pull Force, Case 1: 37.70 lbs # Pull Force, Case 2: 37.70 lbs # Surface Field: 6403 Gauss # Max Operating Temp: 176ºF (80ºC) # Brmax: 13,200 Gauss # BHmax: 42 MGOe this is not a homework problem...im an amateur windmillist this is what i have...im trying to find output at 1rpm of a 34inch turbine with 21 coils (7 coils each phase) if someone will tell me how to plug in the equations i could do the math, but this is beyond me...if you need more info i will get it. please help.
