On the relationship between slit width and light diffraction
In a light diffraction experiment, using a laser and a diffraction grid we can observe that the slits produce a diffraction pattern when the light from the laser goes through it. I have the hypothesis ...

Do twisted pair wires create a helical shaped magnetic field if parallel electrical currents are run through the two wires?
I would like to know if the shape of the magnetic field around twisted pair insulated wires will be a helical shaped magnetic field if both wires have parallel electrical current running through them.

How do you determine power flow direction in a transmission line?
Below is a picture of a typical transmission line(about 200 kV). Is there a simple physics experiment which can be performed safely near the line, to determine the power flow direction. Or in other ...

Anisotropic Behavior of Glass in the Faraday Effect Experiment
I'm currently working on an experiment that uses the Faraday effect to determine the Verdet constant of SF-57 glass.
Basically, similar to the photo above, I have a LED that generates a 405nm light. ...

If we use Negative Ions as probe for nuclear reactions, will they get deflected?
I am studying the basics of Nuclear Physics, and just read about the Rutherford experiment.
My question is if we use Negative Ions as probe for nuclear reactions, will they get deflected?
If yes then ...

Weight of magnet depends on its N-S orientation?
I weighed a Neodymium disc magnet and found that it weighs about $1$ mg more when the north pole is upwards than when the south pole is upwards.
Can this be explained by "conventional" ...

Measurement of Electric field
I am aiming to measure the strength of an electric field at different positions in space. The electric field is generated by a coil, which is driven by an AC current. This work is based on this paper: ...

Cavendish experiment and electromagnetism
Flat Earther's deny the Cavendish experiment at all costs, and it's useless to debate with them, but I learn a lot by watching the nonsense they talk about and studying it. They say that the masses ...

Atoms in the cavendish torsion balance
Some people who try to deny the Cavendish Experiment say that the masses attract each other because of the atoms, not gravity. Doesn't an atom have a null electric field by nature? Is there any other ...
