And what makes neodymium magnets so much stronger than the ceramic magnets we played with as children? To understand the answers to these questions, it helps to have a basic definition of a magnet. Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt...

Sephora’s program is a great example of an engaging, tiered program with multiple touchpoints and rewards. Customers can earn points for purchases, and as they accumulate them, they move up through different tiers, unlocking better rewards and access to new product offers. Moreover, the program...
It’s useful to understand how Raphael stores paths for the purpose of debugging and getting information about the path after the fact. (Perhaps you want the coordinates of the first and last point in order to draw some objects at either end of a line.) In fact, you can choose to deliv...
Reconnect the servo power, and use the Control Center to test that you can move the monitor from horizontal to vertical, that the servo can pull free of the latches, that the speed on the servo is adequate so that it both turns freely, but doesn’t hit the bumpers so hard it bounces...
Any small movements in the water might cause the cork to move, so you want the water to be as calm as possible. When the water is calm, carefully place the cork in the centre of the bowl so that the needle is on top and can move freely. If it starts moving towards the edge of ...
consists of multiple metal coils. The coil wire is coated in enamel to prevent short-circuiting as it’s wound in multiple loops. When an electrical current passes through the stator coils, it generates a magnetic field that interacts with the permanent magnets on the rotor, creating rotation....
Just like CCD cameras they are sensitive to IR radiation [23]. In addition they have a high dynamic range [28], i.e. very bright objects and very dark objects can be recorded satisfactorily at the same time. CMOS cameras have disadvantages as well. Because each pixel comes with a piece...
Rails will cause Boxes to be pushed in mandatory directions, depending on the layout of the Rail. For example, a Rail that is vertical means that the Box can only be pushed up or down while on the Rail. A Player can move along a Rail freely. ...
Because electrons cannot freely move, the two surfaces can remain charged for a long time, unless they are exposed to an electrically conducting material. If an electrically conducting material like metal is touched to the charged surfaces, the electrons will be able to move freely, and the char...
