An explorer somewhere on Earth walks 10 miles south, 10 miles east, and 10 miles north and yet ends up at the same point where she began. Where could the explorer have started to allow that result? Is there a second answer to this problem?
There are many answers to these problems if you allow such devices as treadmills, continental drift, and worm holes. At the end of the post are answers that require only spherical planets.

Here is Some Science for YOU (Written by the Physic’s professor of Wayland Academy)
Lenz’s Law
Induced current is in such a direction that the magnetic effects of the current opposes the change that caused the current.
Magnetic fields are due to the forces of repulsion and attraction between charges. It’s not a new kind of force and there are no fundamental units or quantities involved. It’s a relativistic effect due to the motion of charges. Wherever there is a magnetic field, there are moving charges causing the field.
A magnetic field is an alteration of space around moving charges which causes a force to be exerted on other moving charges. Atoms contain moving charges and the charges display two types of motion, each of which contributes a magnetic field. In most atoms, or at least in most substances, these magnetic fields cancel each other out or come close to doing so. Ferromagnetic materials are an exception.

1. a. The explorer started at the north pole.
1. b. The explorer could also have started 10 miles north of a ring around the south pole that has a circumference of 10 miles (or any other distance that divides evenly into 10 miles.)
