Science Buddies: "Ask an Expert"

What is the relationship between magnets and electricity?

Gloken,

Welcome to Science Buddies. You ask a very good question, but also an extreamly large subject. The relationship you refer to is responsible for and integral to a significant amount of our modern day existance. There are entire courses of study devoted to just this topic.

In a nutshell, however, Faraday's Law states that a change in a magnetic field around a coil of wire will induce an electric current in the wire (the basis of electromagnetic generators)...and vise versa, an electric current through the coil of wire will create a magnetic field (this is the basis of electromagnets).

Focusing on the "Magnetic Field" line of topics down to "Faraday's Law", and reading the "EMF" and "Maxwell's Equations" sections should get you started on the basics of this relationship.
