If the north and south pole change direction or rotate would that effect the earth?
The magnetic field of the Earth serves a useful purpose in deflecting Solar radiation. Without the magnetic field there is much more charged-particle radiation striking the surface. The auroras would occur everywhere instead of at the magnetic poles. Compass needles wouldn't work, and then they would flip direction. The magnetic field IS DECREASING and could go to zero and reverse sometime in the next few tens-of-thousands of years. It may be overdue for a flip.

How heating a bar magnet would change its magnetic field?
singing
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
How far is the magnetic south pole from the geographic north pole?
Half the world away (8000 miles as a neutrino would fly, 12,500 miles as a bird would fly.)
How is the magnetic North Pole different from the geographic North Pole?
Magnetic north pole is where your compass will point. Geographic North pole is at the "top" of the globe. If you put a pole straigh thru the earth from the north pole to the south it would be a straigh line.Magnetic north and south poles can and do move because the eath's magnetic field flucuates.The geographical or 'true'' north pole is the point where the Earth's axis line touches the Earth's northernmost surface. That is somewhere in the (northern) Arctic Ocean.The location of the magnetic north (and south) pole 'travel around' over time. Today the magnetic south pole - strange as it may sound - is located in the north of Canada, the magnetic north pole in southern Antarctica.
How would benchmark results change if you had only a 100 dollar budget?
The performance results would decline, but the selection process would remain the same
What would happen if walkers did not adjust their compass readings to account for magnetic variation?
They would not arrive at the correct location. True north refers to the rotational pole. Compasses point roughly towards the magnetic pole. I say roughly because geographic and man made features can distort the magnetic waves. The rotational and magnetic pole are not at the same place. Most maps are drawn according to the rotational pole (true north).
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
Why is it important to take declination into account of you are traveling with a compass?
Unlike the geographic poles, which are always in the same place, the magnetic poles change location throughout the history of earth. So when using a compass to map or explore the Earth's surface, you need to make a correction for the difference between geographic nor and magnetic north.
Can the magnetic poles change during your lifetime or is the change gradual and what are the impacts?
The magnetic poles are showing strong signs of switching. About every half a million years, the magnetic poles would switched position. It seems that we are overdue since the last switch is about half a million years ago. The past century, the magnetic strength had dropped by 5%.
What happens to the magnetic field of a wire when you change the direction of the current of the wire?
If iron piece is place in its field, the direction of the magnetic lines of force change towards North and South as in the case of a magnet. North represents North Pole and South for South Pole.
