| 1 | Yet another longstanding mystery is why Mercury has a magnetic field. | |
| 2 | Exposure to radio waves and fluctuating magnetic fields also have their potential dangers. | |
| 3 | Another interesting property of superconducting materials is that they will levitate in a powerful magnetic field. | |
| 4 | Further imagine that this pipe is not made of metal but a transparent magnetic field. | |
| 5 | These are huge variations in particle intensities, magnetic field strength and electric field strength," Lyons said. |
