This is a list of gravity hills and magnetic hills around the world. A gravity hill is a place where a slight downhill slope appears to be an uphill slope due to the layout of the surrounding land, creating the optical illusion that water flows uphill or that a car left out of gear will roll uphill. Many of these sites have no specific name and ...
Visitors experience demonstrations that appear to defy gravity, on the short but steep uphill walk and inside a wooden building on the site. It is a popular tourist attraction, and gained recognition as a roadside "gravity box" or "tilted house". [3] [4] The site is what is known as a gravity hill and was the first of its kind to be built in ...
The magnetic moment and the magnetic field of the electromagnet are proportional to the number of loops of wire, to the cross-section of each loop, and to the current passing through the wire. [47] If the coil of wire is wrapped around a material with no special magnetic properties (e.g., cardboard), it will tend to generate a very weak field.
Some quantities are known as several different names such as the magnetic B-field which is known as the magnetic flux density, the magnetic induction or simply as the magnetic field depending on the context. Similarly, surface tension can be denoted by either σ, γ or T. The table usually lists only one name and symbol that is most commonly used.
A new image of the black hole that lies at the center of our Milky Way galaxy shows that it is surrounded by a strong, twisting magnetic field. New image reveals spiraling magnetic field around ...
The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself. [9] [10] The leading theory is that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts. [9] [10] [11] This is supported by the observation that they are mostly found near the surface of the Earth, rather than buried at great ...

First things first, just about every household in the ‘80s had a shelf full of board games. But there was one common denominator you could find on nearly every one of those shelves: Trivial Pursuit.
