A compass is not made of the same substance as a magnetic field, nor is it sent or chosen by the north pole, but it is accurately sensitive to the pull and direction of the magnetic field within which we live. (religion-online.org)
The study shows that the initial direction of the magnetic field observed by Voyager 1 is deflected by the heliopause, like an elastic cord wrapped around a beach ball. (sciencedaily.com)
By changing the direction of the magnetic field several billions of times a second the scientists were able to make the «mirror» vibrate at a speed of up to 25 percent of the speed of light. (religion.blogs.cnn.com)
