Two parallel conductor rails with negligible resistance are
connected at one end by a resistance resistor R=1.40 Ω, as shown in
the figure. The rails are placed in an upwardly directed magnetic
field B= 5.00 T , which is perpendicular to the plane of the rails.
This magnetic field is uniform and independent of time. The
distance between the rails is l= 0.20 m. A conductor bar slides
without friction on the top of the two rails at a constant...

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...
