Electromagnetic induction with a two-magnet assembly
I performed a bunch of experiments where I let a two-magnet assembly free fall through a vertical solenoid. The magnets are shaped like rings, are identical in size, and are held in place - with a ...

How do we know that parity is conserved in electromagnetism?
Theoretically it is well established that parity is conserved in electromagnetism, that is the lagrangian is invariant under parity operation.
What I would like to know is what experiments enforce ...

What is a reference for a practical experiment for existence electric field wave and magnetic field wave in an electromagnetic wave?
Maxwell equations lead to simultaneous perpendicular oscillations of electric field as well as magnetic field with same amplitude and “wavelength”. But, they do not guarantee any propagation of these ...

How can I calculate magnetic flux density/field strength with given Force on a current carrying wire, Current and length of wire, using $F=BIL$ eq?
For my student experiment we had measured the force that magnets have on an electromagnetic copper wire with the length of 20 cm, as the current increases, the magnets push down the copper wire more ...

Paul Dirac on Dimensionless Physical Constants and $\alpha\sim\frac{1}{137}$
Paul Dirac gave his viewpoints on the dimensionless constant (click to see the youtube video). For example, he mentioned the fine structure constant
$$
\alpha\sim\frac{1}{137}.
$$
It is not clear that ...
