Can every mass obey the Newton's 3rd law?
As in, if we were able to produce a very huge amount of force on a very small body, would it push back with the same force? Given it doesn't break or disintegrate.
Like if we electromagnetically put ...

What is the flux $\Phi$ enclosed by cyclotron orbit, which can express the quantization rule?
Suppose an electron (mass $m$, charge $e$) in the xy-plane with $B=(0,0,B)$ (The classical EOM result in circular orbit). Using the Bohr-Sommerfeld quantization rule we can find that $E_n = (n+1/2)\...

An electron moving through a magnetic field [closed]
An electron, that has been accelerated from rest by a potential difference of $250\ \rm V$, enters a region of magnetic field of strength $0.12\ \rm T$. Show that speed of the electron after ...

When an electron achieves a velocity q, does the electron lose it's velocity at the expense of creating magnetic field?
When an electron achieves a velocity $q$ by a force $F$ , does electron lose it's velocity at the expense of creating magnetic field? And what is the theory of electron moving without magnetic field ...

How can magnetic field change direction, do not changing the velocity of particle?
I know that electron has spin and momentum. Momentum is $vm$ and $v $ is $\dfrac {dx,y,z}{dt} $. So how it could be possible to affect the particle the way it will change only direction, instead of ...

Do the concentration of electrons in a circuit affect the magnetic field?
Beware that I am going to make a few statements and not all if any of them are necessarily true or possible. I do not know whether my premises or my main question makes sense.
Assume that an AC-coil ...

Point particle with a magnetic dipole?
I have read these questions:
Are contravariant basis vectors and basis 1-forms identical?
Where John Rennie's answer says that electrons do have an electric dipole moment and we imagine that in math ...

Permanent magnet's magnetic field arises due to the magnetic dipole moment of the electrons inside the magnet?
THIS QUESTION IS NOT A DUPLICATE OF THIS:
Real QM cause of magnetic dipole moment
Because that question asks about the cause of the magnetic dipole moment of an electron.
This question is asking ...

Can a moving electron produce a magnetic field stronger than what caused it to move in a circle
We know that when an electron is made to enter a magnetic field, say $B_1$, with some velocity at a right angle to $B_1$, a force acts on it which makes it rotate in a circle. But a moving electron ...

Why is the magnetic field dependent on the current inside the Amperian Loop?
I visited this website simulating the magnetic field inside and around a pipe. I understand that there is no current flowing at the center of the pipe, thus there is no magnetic field generated ...

Path of an electron in magnetic field [closed]
Can we describe the path of an electron (or any subatomic particle) inside, say magnetic field?
We generally described in terms of classical laws that this path will be spiral or circular.
But path-...

Why is the magnetic field created? [duplicate]
From Oersted experiment we know " When an electric current is passed through a conducting wire, a magnetic field is produced around it." An electric current is a flow of electric charge or electron. ...
