| To demonstrate the first of these behaviors, hold a magnetic compass near a wire conducting a DC current. |
| It affixes to any outside surface of a car, and doesn't cause damage like magnetic signs or bumper stickers would. |
| Iron creates the magnetic field and copper wires carry away the current generated. |
| The most accurate atomic clocks available today use the cesium atom and the normal magnetic fields and detectors. |
| The aircraft's magnetic compass probably appeared to be working well, and setting up the astrocompass would have been a nuisance. |
| By touching the white boards or by using magnetic pointers teachers and pupils can alter and rearrange the information displayed. |
