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.
What happens to a current carrying wire in a magnetic field if the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
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.
What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
Earths magnetic field does not affect what?
Other planets
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.
The alignment of iron-bearing minerals in rocks when they formed reflections the fact that earths has reversed itself several times in its past?
magnetic field .
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.
About how long ago was the last time earths magnetic field reversed?
About 41,000 years ago.
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?
magnetic field.
What happens to a current carrying wire in a magnetic field if the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
Bands of rock the seafloor showing alternating magnetic orientation indicate earth's magnetic field has?
reversed itself in the past. hth :)
Can the magnetic field of Earth be reversed How?
No
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.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
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.
