WebAug 3, 2024 · At Earth’s surface, the magnetic field forms two poles (a dipole). The north and south magnetic poles have opposite positive and negative polarities, like a bar magnet. The invisible lines of the magnetic field travel in a closed, continuous loop, flowing into Earth at the north magnetic pole and out at the south magnetic pole. WebApr 1, 2024 · magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field. Magnetic fields force moving electrically …

WebA field models what an object would experience related to a force at a given point in space. A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region. WebDec 20, 2016 · In this paper, the effect of a tapered magnetic field on the expanding laser-produced tantalum plasma was experimentally studied to concentrate laser-produced plasma on a beam axis. Experimental results were compared between the tapered magnet and a straight solenoid. Ion current was measured with laser shot on the magnet axis … if c statement
