Build a simple Electric Motor
... Motors take electrical energy, and convert it into mechanical or moving energy. Basically, motors take the electrical energy from an electricity source, such as an outlet or battery, and change that energy into something that spins, moves or does some sort of work. We interact with all sorts of moto ...

Magnetism is a force that acts at a distance.
... If you bring a magnet near a paper clip that contains iron, the paper clip is pulled toward the magnet. As the magnet nears the paper clip, the domains within the paper clip are attracted to the magnet’s nearest pole. As a result, the domains within the paper clip become aligned. The paper clip deve ...

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.
