Electromagnet

As an erstwhile writer and inventor in the realm I’d be most happy to participate but don’t know how to begin. Robin you might suggest pertinent aspects

Robin where are you

Try again, but ask q’s or suggest a hot topic

Electromagnet is useful device it use in many place like in medical equipments, security system and vehicles.

Forgive me again Robin but we’re just not quite sure how to respond

The Electromagnet is used in many fields like electronics,electrical,medical etc.The quality if these type of wires are very good and lasts for a very long time.

Clearly Robin and by the sheerest coincidence my field was medical electronics; and indeed the quality of the parts, esp the wire used, is important to their longevity

But is there any other way in which we having had some experience in the field might further contribute

If from a theoretical point of view I’ve always found it remarkable that the magnetic field is a relative phenom depending on mutual motion: That is, we have one where the electron is moving but not if we’re moving with it
