WebBefore the solar wind was discovered, the Earth's field was thought to be symmetrical, resembling that of a huge bar magnet, fading off indefinitely into space. However, we now know that the solar wind shapes the outer regions of the Earth's magnetic field, and that the field is sharply bounded. WebIn one directional paths, you can easily find the direction in which the object is moving towards, but in circular or wiggly paths, the object changes its direction constantly. Therefore, we take tangents to determine which direction the object was moving towards at that particular point.
