A tube is placed inside a coil, with the end fitting then installed inside. A capacitor bank dumps current through the coil to generate a strong electromagnetic field. This field is opposed by a ...

Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez] demons… ...

Extremely strong electromagnetic fields, that is. The theory of quantum electrodynamics, which describes interactions of electrically charged particles and light, has been checked to painstaking ...
