We are just starting our new section about magnetism and it's been reported that the Earth's magnetic north pole is on the move.
- If the pole is moving at a rate of 40 miles per year, then how many feet per day is it creeping towards Russia?
- Is this the fastest rate at which the pole has traveled in one year?
- What is the slowest?
- If the rate at which the pole moves varies from fast to slow, what is causing it to vary its speed?
