In 2014, about how far in meters would you have to travel on the surface of the earth from the north magnetic pole to the geographic north pole? take the radius of the earth to be 6378.1 km.

267.07 km

Explanation:

We have given the radius of the earth = 6378.1 km

In 2014 the difference between the magnetic north pole and geographical north pole is 2.40°

2.40°

We know that linear distance is given by

So we have to travel 267.07 km in going from magnetic north pole to geographic north pole

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
