Web25 nov. 2009 · Magnetic Field from a Finite Solenoid Hello I need to calculate the magnetic fied from a coil. The solenoid has a finite side, and its length and number of turns are known. However, I can't find out how to do the calculation. I know that the B-field in the middle is equal to u0*n*I but I don't understand how to find the result, using Ampere's law. Web3 aug. 2024 · At Earth’s surface, the magnetic field forms two poles (a dipole). The north and south magnetic poles have opposite positive and negative polarities, like a bar magnet. The invisible lines of the magnetic field travel in a closed, continuous loop, flowing into Earth at the north magnetic pole and out at the south magnetic pole.
