The person's feet seem attached to the floor as if by a magnet. In magnetic gait, each step is initiated in a "wresting" motion carrying feet upward and forward. Magnetic gait can be visualized in terms of a powerful magnet being forcefully pulled from a steel plate. [citation needed]
The screen-door effect (SDE) is a visual artifact of displays, where the fine lines separating pixels (or subpixels) become visible in the displayed image. This effect can be seen in digital projector images and regular displays under magnification or at close range, but the increases in display resolutions have made this much less significant.
The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant. The direction of an induced current can be determined using the right-hand rule to show which direction of current flow would create a magnetic field that would oppose the direction of changing flux through the loop.

The door of a microwave oven has a screen built into the window. From the perspective of microwaves (with wavelengths of 12 cm) this screen finishes a Faraday cage formed by the oven's metal housing. Visible light, with wavelengths ranging between 400 nm and 700 nm, passes easily through the screen holes.
