Magnetic Field In Wire??

Question

I am wonderng, which would have the stronger magnetic field, an uninsulated wire carrying current
an insulated wire carrying the same current.

( Not sure if I can make my electromagnet stronger by removing the insulation).

Answer 1

No it doesn't matter. insulators don't interact with magnetic fields at all. The magnetic field of a wire has to do with the current flowing through it. Try using a larger diameter wire (lower resistance=higher current = higher magnetic field) wrapped more times 100 loops is about 10 times stronger magnet than 10 loop. Also wires used to make electromagnets should not have bulky insulaion- the coil has to be tight so the magnetic fields of the loops can sum.

Hope it helps

Answer 2

Hi Rhamm618!
We know that the electric and magnetic fields are mutually perpendicular. And also that the magnetic field is get by applying a current to the non insulating wire.
Hence an uninsulated wire which carries current giving an strong magnetic fields.
The answer is in my knowledge.

Ok Bye.

Answer 3

if its just some highschool physics experiment, it wouldnt make that much difference

and it shouldnt affect the magnetic field even if you remove the insulation...

and dont you think it would be safer to leave the insulation on? dont get electrocuted!

Answer 4

I don't think it makes any difference
