For questions that utilize the concept of magnetic fields (commonly denoted by the letter B), or for questions whose answers likely involve magnetic fields. More specific than the [magnetism] tag, as questions about the phenomenon & theory of magnetism do not necessarily involve the discussion of fields.

Magnetic Force and Magnetic Field - Conservative or Non Conservative? [closed]
I understand that this question is asked many times on PSE, but my questions which I ask below are slightly different. I have read almost all the discussions on PSE on the topic but a few questions ar …

Ideal and Real Solenoid - Magnetic Field difference
The above graphs show my textbook comparison in the magnetic field inside an ideal and real solenoid. In my opinion, even the graph of an ideal solenoid should be the same as the real solenoid as sho …

What do we mean by magnetic field energy? Does this magnetic field energy in a current carry...
Let me take an example to elaborate my question. Suppose we have a simple circuit with a battery (E) and a resistance (R). Current will be flowing in the circuit, I = E/R. Now, we know that that if th …

What do we mean by magnetic field energy? Does this magnetic field energy in a current carry...
For a very small duration of time, when current was growing in the circuit, the current was variable, due to which the magnetic field associated with it was also variable, due to which induced non con …

Where does the Magnetic Field Energy come from, in case of a charged particle moving with co...
This response has its primary inspiration from the response of V.F. I have further added my own thoughts into it.
A charged particle moving with a constant velocity has a magnetic field energy assoc …

Where does the Magnetic Field Energy come from, in case of a charged particle moving with co...
A charged particle moving with constant velocity creates Magnetic Field around it. If there is Magnetic Field, then there must be Magnetic Field Energy. The question is, where does the Magnetic Field …

How does a time varying magnetic field confined in a cylindrical region produces induced ele...
We know from Faraday's Law of Electromagnetic Induction that due to Time Varying Magnetic Field (TVMF), a non conservative electric field will be induced.
Now if we consider a cylindrical region in w …

Is the magnetic field energy around a current carrying wire is similar to the electric field...
What I mean by this question is, as we say that the electric field energy around a charge is the self energy of the charge, similarly can we say that the magnetic field energy around a current carryin …

Is the magnetic field energy around a current carrying wire is similar to the electric field...
It would be inappropriate to say that a current carrying wire would have Self Energy, in form of Magnetic Field Energy. Self Energy of charges are different from this concept.
In electrical circuit …

Everywhere in the literature I have across, I find that whenever the discussion of the Induced electric field comes, it is discussed around a cylindrical time-varying magnetic field. The induced elect …

Consider the example shown above. Here we have connected an active inductor, in which the initial current is "I", to a resistance, with the help of a switch and close the switch at t=0. We know and i …
