The earth's magnetic moment is 8 x 1022 A-m2. If that moment
were created by a loop of wire going around the earth (r = 6378
km), what current would need to go through the wire in A?
The wire loop would be on the equator. True or false? Why?
Whether on the equator or close to the equator, which direction
would the current travel? Why?

Earth has a magnetic dipole moment of 8.0 × 1022 J/T. (a) What current would have to be produced in a single turn of wire extending around Earth at its geomagnetic equator if we wished to set up such a dipole? Could such an arrangement be used to cancel out Earth's magnetism (b) at points in space well above Earth's surface or (c) on Earth's surface? Round your answer (a) to 3 significant digits.

Problem 3 a) Find the magnetic field H at the center of a square loop carrying a current I. The side of the square loop is b meters long. b) A circular loop that has a radius a and that carries a current I produces the same magnetic field strength at its center as that at the center of a square loop that has side b and that carries the same current I. Determine the ratio of...

The Earth has two main angular velocities as it moves through space. One is due to its motion around the sun, the other is due to its rotation around its own axis. A. What is the angular speed of the Earth as it revolves around the sun? (answer in rad/s) B. The radius of the Earth's orbit around the sun is about 1.5×108 km. Based on your answer to Part A, what is the tangential speed of the Earth as...

Suppose that the magnetic dipole moment of Earth is 9.7 x 1022 ?/T (a) If the origin of this magnetism were a magnetized iron sphere at the center of Earth, what would be its radius? (b) What fraction of the volume of Earth would such a sphere occupy? The radius of Earth is 6.37 x 106 m. Assume complete alignment of the dipoles. The density of Earth's inner core is 14 g/cm3. The magnetic dipole moment of an iron atom...

Tethers are long dangling wires that use the velocity of a spacecraft through the Earth's magnetic field to generate electrical power. Alternatively, electrical currents pushed through the tether might be used to change the spacecraft velocity for either propulsion or for braking and reentry. Several 'space tether experiments have been flown to investigate the possible use if Faraday's law for power generation and/or propulsion. Examples are the 1996 joint US/Italy effort to deploy a 20 km tether from one of...
