Define Eddy Currents?
If you try to pull a solid piece of some metals (good electrical conductors) quickly between the poles of a strong magnet, you will feel a force pushing against you. This is due to eddy currents. The changing magnetic field sets up induced current flow in closed paths, within the metal, which oppose the change of the magnetic field causing the currents. Will the same thing happen pulling a comb made of the same metal through the magnetic field? No, because these eddy currents cannot form, due to the breaks in the metal - no opposing force is felt.
Newton's Law of Gravitation In 1687, Newton did not "discover" gravity but he did figure out that gravity is universal. It makes a ball fall when you drop it on earth. It also
Gauss' law for magnetic fields (K.F. Gauss) The magnetic flux by a closed surface is zero; no magnetic charges present; in differential form, div B = 0.
