No. Venus has no magnetic field.
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
The Earth's magnetic field and the plant Venus is the same size. Scientist say that Earth and Venus are twin plants.
Venus has a small magnetic field created by the interaction of its ionosphere and the solar wind. This is different from most of the intrinsic planetary magnetic fields (those generated by planetary cores) that are commonly spoken about. Venus either lacks an intrinsic magnetic field or it has one that is in the midst of a polarity reversal.
No, as it has no magnetic field.

Yes
Most importantly to us, the earth has a permanent magnetic field.

Magnetic storage:Yes magnetic tapes are permanent storage and are the best permanent storage. These are very slower storage but are very cheap storage then RAM or other kind of memory.
Venus does not have a magnetic field.
The magnetic domains are aligned
No, as it has no magnetic field.
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
