About Beakmans motor. design equation B, I, N, calculations or mathcad file?

[julee]

I built a Beakman motor and works good. But Iwonder how to calculate :
-Magnetic Induction B(Teslas)?
-Current I(amperes)?
-Voltage V ( volts)

Data:

N= 5 turns
D=9 milimeters( 38 AWG copper wire)
V=1.4 Volts
B= ...? (May be 0.1 tesla)...small Headphones magnet

If any guy have a pc program, mathcad file or java simulator for this small values. Please let me Know ..and I send you a free motor beakman...(I think the smallest motor..)

Unfortunately, there is no simple way to calculate magnetic induction B, current I, and voltage V from the data provided. You would need to know the coil resistance and the magnetic field strength of the magnet being used in order to accurately calculate the values.

Hello Julee,
Congratulations on successfully building a Beakman motor! It's always exciting to see your hard work pay off. As for calculating the magnetic induction (B), current (I), and voltage (V) for your motor, there are a few equations and factors that you can use to determine these values.

First, let's start with magnetic induction (B). This can be calculated using the following equation:
B = μN * I / l
Where μ is the permeability of the material (in this case, air), N is the number of turns in the coil, I is the current, and l is the length of the coil. In this case, the length of the coil is not given, so we will have to estimate it based on the diameter (D) of the coil.

Next, we can calculate the current (I) using Ohm's Law:
I = V / R
Where V is the voltage and R is the resistance. The resistance of the coil can be calculated using the following equation:
R = ρ * l / A
Where ρ is the resistivity of copper (1.68 x 10^-8 Ωm), l is the length of the wire (which we estimated earlier), and A is the cross-sectional area of the wire (calculated using the diameter of the wire).

Finally, we can calculate the voltage (V) using the following equation:
V = B * l * v
Where B is the magnetic induction, l is the length of the coil (estimated earlier), and v is the velocity of the coil (which we will assume to be constant).

I would suggest using a program like Mathcad or a simulator to input these equations and values to get a more accurate result. I do not have a specific program or file to recommend, but a quick internet search should provide you with some options.

I hope this helps in your calculations and understanding of your Beakman motor. Keep up the good work!

Best regards,
