Magnetic field around a current
... Conceptual Example 7 An Induction Stove Two pots of water are placed on an induction stove at the same time. The stove itself is cool to the touch. The water in the ferromagnetic metal pot is boiling while that in the glass pot is not. How can such a cool stove boil water, and why isn’t the water in ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
