Of course-it's like blood-(within our bodies)when we overexert ourselves our vessels constrict-I could take this and go in so many directions you'd go nuts!!Cheers!

The magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law. The expression for the magnetic field is
B=constant I/2 pi r where constant=mu zero
I is current in amperes
and r is the radial distance
So as I in amperes increases so does B in Tesla

Yes. The more current there is the stronger the magnetic field generated. Coiling the wire multipies it even more. This is why
an electromagnet will have wire coiled around an iron rod, typically.

The above consensus is accurate.
The side rule though is the magnetic field intensity is subject to shielding surrounding the wire.

yes obviously it does...
if B is the magnetic field, i the current, dl the length element, r the distance and a the angle between dl and r then
B = idlsina/r^2
so u can see that intensity of magnetic field is directly proportional to the intensity of current
ps the formula written above is the mathematical relation of the Biot-Savart Law

that is 60 Hz certainly, same to contained in the homestead. that is easily extremely basic to inductively couple a loop of cord to a transmition line. you are able to paintings all of it out from Ampere's regulation and Faraday's regulation instantly. do not difficulty about radiation (it truly is the D time period contained in the latter). that is strickly an wide to field effect because 60 Hz is so sluggish. of direction, you pick to comprehend a thanks to apply those equations to get that formula you pick. also, the loop would might want to be particularly large and conspicuous, and that is a criminal offense. you'd be stealing electrical energy.

yep, the stronger the current, the stronger the magnetic field.
