Electricity can produce Magnetic effect. Magnetism can produce Electricity. That's what Electromagnetism is, but Marvel Villains Electro & Magneto have never used each other's powers. I think this is because the general public is unaware of Electromagnetism.

In 1933, Walther Meissner and Robert Ochsenfeld discovered that a superconductor repels a magnetic field when it is cooled below its transition point. #Poetry #Science #History #Electromagnetism #Superconductor #Meissner #Ochsenfeld (https://sharpgiving.com/thebookofscience/items/p1933.html)
A classical #electromagnetism experiment in this time of the year (i.e. towards the end of my EM course): magnetic breaking acting on a falling magnet (home version).
The left magnet just falls in free fall, the right one gets braked by the induced magnetic field within the aluminum cylinder (mad just sticking together three aluminum foil wraps for kitchen use).
Where is the induced magnetic field coming from? From #Faraday's induction law of course!

E.g. In #electromagnetism, "magnetic field" can be used to mean either B or H fields. It doesn't help that in many cases the differences is merely a prefactor.
As other have said, the only thing to do is explain that the ambiguity or confusion exists, and introduce (or reiterate) a #terminology that both clarifies & which is more explanatory.
FWIW, B is the true magnetic field, and H is a magnetic excitation field (the counterpart of the electric excitation/displacement field D).
In 1907, Pierre Weiss explained that atoms in a ferromagnetic material align in groups called domains. #Poetry #Science #History #Electromagnetism #Magnetism #Weiss (https://sharpgiving.com/thebookofscience/items/p1907d.html)
