Homework Statement
Hey so I've made a motor that looks and works exactly like the one in this video
The assignment is asking me how I would go about finding the angular velocity, specifically " Analysis of the energy changes involved in the motor to work out the speed/ or angular velocity"
The problem is I have no idea how to do this, I asked my physics teacher and he said start from F= B I L sinθ but its been very confusing, I think I may not have some of the values I need and even if I did I'm sure its not as simple as just substituting them into the equation.
Motor runs off a battery of 12 V, 1.3 amps. It has 120 coils of copper wire (estimate) and the angle for sinθ is 90 degrees
Homework Equations
F= B I L sinθ
The Attempt at a Solution
[/B]
I don't know which values I need from the motor. I run it off 12V and a 1.3 amp battery, I have a multi-meter and a spring balance, I don't know the magnetic field strength of my magnets or the electromagnets I've made. I forgot to count the amount of coils, but the teacher marking it isn't going to know either so I'd estimate around 120 coils. If anyone can help me out it'd be great, ask me for information about the motor and I'll be happy to get the values for current, voltage, resistance etc and reply back
