Hi all.
- A magnet produces a magnetic field that can be detected by a proper instrument, perhaps 1 metre away if powerful enough; Yes or no ?
- If that magnet has a coil wound on it, and that coil is fed with AC, its field becomes magnetic + electromagnetic, and can be detected by the proper instruments, perhaps 1 metre away; Yes or no ?
- If the magnet is removed from the coil and an iron core is placed instead, the coil fed with AC will produce an electromagnetic field only, and can be detected by the proper EM instrument; Yes or no ?
