Alguém poderia me auxiliar nesta questão? Calcule o módulo do campo magnético em um ponto a 25,0 cm de um condutor longo e fino que transporta uma corrente de 2,00A.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
