Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
How many times has Earth's magnetic field reversed?
50 times
When the Earth's polarity is reversed is the Coriolis effect also reversed?
No. The reversal of polarity is a reversal of Earth's magnetic poles. The Corilolis effect is a direct consequence of Earth's rotation and is not affected by the magnetic field.
The alignment of iron minerals in rocks when they are formed reflects the fact that Earth's has reversed itself several times in the past?

What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
How is the force affected when the current is reversed in a magnetic field?
The magnetic field would reverse.
What happen to an electromagnet's field if the direction of the current ic reversed?
In that case, the magnetic field will also be reversed.
How long ago did the earths magnetic field reverse itself?
The last time that Earth's magnetic field reversed itself was 780,000 years ago. See the related link for two timelines showing geomagnetic reversals in Earth's history.
