Lenz Law in a single-phase pulsed induction generator

[DeepCut]

Hello.

I have made a little generator which is running quite efficiently but i would like to see if i can squeeze one or two percent more out of it.

My physics knowledge is very poor and i wonder if anyone could tell me how Lenz's Law is affecting the device.

I will describe it then attach some photo's.

I'm using a signal generator to pulse a 'drive coil' with a square wave.
Above the drive coil is a diametrically-magnetised, cylinder-shaped magnet placed horizontally.
Around the whole thing is the 'output coil'.

The pulsing magnetic field of the drive-coil rotates the magnet on it's shaft, the rotating magnetic field induces a current into the output coil.

Here are some photos :

I find it hard to visualise the Lenz effect, if anyone could help me i would greatly appreciate it.Thank you.

Hello,

Thank you for sharing your project with us. It is always exciting to see new ideas and inventions being developed.

From your description and photos, it seems like you have built a simple generator using the principle of electromagnetic induction. Lenz's Law is indeed affecting your device, as it is a fundamental law of electromagnetism that describes the direction of induced currents in relation to the changing magnetic field.

In your generator, the pulsing magnetic field of the drive coil induces a current in the output coil. This current creates its own magnetic field, which interacts with the magnetic field of the rotating magnet. According to Lenz's Law, this interaction will create a force that opposes the change in the magnetic field, thus reducing the efficiency of your generator.

To improve the efficiency of your generator, you can try different strategies such as increasing the number of turns in the output coil, using stronger magnets, or changing the shape and positioning of the magnets. It would also be helpful to perform some calculations to determine the optimal parameters for your generator based on the principles of electromagnetism.

I hope this helps and good luck with your project! If you have any further questions or would like more specific advice, please don't hesitate to reach out.
