Right now (late 2015), the difference is about 256 miles.
The geographic north pole is the point where the north end of the
Earth's rotation axis sticks out of the ground. As long as the Earth
continues to spin on the same 'pencil', the geographic poles don't move.
The magnetic north pole is the point on Earth that magnetic compasses
point to. The magnetic poles are the result of the flowing, shifting liquid
iron in the Earth's core, and they move. The magnetic north pole is presently
somewhere in the Canadian Arctic territory, about 256 miles south of the
geographic pole, and moving westward towards Russia at about 35 miles a year.
A square loop whose sides are long is made of copper wire of radius , given the resistivity of copper is . if the magnetic field perpendicular to the loop changes at a constant rate of I = 14.029 mA.
The basic characteristic of a substance that measures how effectively it resists an electric current is called electrical resistance. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. Electrical resistance is a basic property of a material that measures how strongly it resists an electric current. The SI unit for electrical resistance is the ohmmeter.
We use magnetic field as a tool to describe how the magnetic field is distributed in the space around and inside something of a magnetic nature. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. An ohmmeter is a unit of electrical resistance in the SI system.

The complete question is :
A square loop whose sides are 6.0-cm long is made with copper wire of radius 1.0 mm. If a magnetic field perpendicular to the loop is changing at a rate of 5.0 mT/s, what is the current in the loop?
Answer:
having sexual intercourse helps most people from what I've seen.
Answer:
17.78 m/s
Explanation:
Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.
1 km = 1000 m, so 16 km is 16000 m
0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.
Thus:
average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s
