... would always align itself so that it pointed approximately in the North/South direction on the Earth. We now know that this is because the Earth is a big magnet due to currents inside the Earth. Thus, people were using compasses for navigation long before we had any fundamental understanding of the ...

... You can think of the nail as a collection of little magnets that are randomly aligned. The magnetic field of the coil aligns these little magnets giving a larger field than that of the coil alone. We say that the nail becomes “magnetized”, but the effect is not permanent. ...

... Remember that the density of electric field lines per unit of area gets larger in the areas where the field is stronger, so the electric flux, showing the number of electric field lines crossing the given surface, is EA . However, this is only true if the lines are perpendicular to the surface. ...
