Question

10. El rabo del campo magnético terrestre es estirado por el viento solar de manera que queda el campo norte apuntando alejandose de la tierra y el campo sur apuntando hacia la tierra El campo magnétic a esa distancia tiene un valor de densidad de flujo magnético cerca de 0.25 Gauss. El espacio es el mismo medio en ambos lados del campo magnético pero los campos no pueden existir de esa forma sin una hoja de corriente. Si supones que la hoja es infinita, determina la magnitud de la densidad de corriente

The tail of the Earth's magnetic field is stretched by the
solar wind so that the north field is still pointing
moving away from the earth and the south field pointing towards the earth.
The magnetic field at that distance has a density value of
magnetic flux about 0.25 Gauss. The space is the same
medium on both sides of the magnetic field but the fields do not
they can exist that way without a current sheet. If
you assume that the blade is infinite, determines the magnitude of the
current density.

Answer 1

If you assume that the blade is infinite and the earth's magnetic field is stretched by the solar wind so that the north field is still pointing moving away from the earth and the south field pointing towards the earth. Then it is about 25 to 65 microteslas.
