if magnetic field induce current then why satelites or space ship doesn't gets electrified due to earth magnetism

A magnetic field doesn't always have a voltage associated with it. Voltage can be generated by a changing magnetic field, or when the potential between two areas are high enough (e.g. lightning). However, this does not normally occur naturally.

The field is extremely weak and the coils needed to generate appreciable current would probably be horribly large and heavy. Plus it would create current by stealing orbital energy from the satellites, and they would slowly fall from orbit.
