As you move away from an ocean ridge, the rocks get older.
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
The Earth's magnetic field is called the Magnetosphere. Loops of magnetic energy coupling the north and south pole that trap energetic subatomic particles are called the Van Allen belt.
No. The magnetic fields of objects such as planets are due to currents withing their molten interiors. Asteroids are completely solid and so do not have magnetic fields.
Both magnetic materials and moving electric charges induce magnetic fields.
a part of the earths structure causes it to act like an electromagnet
no
because of electrons
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
The Magnetic Fields was created in 1989.
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
magnetic fields are essential to production of electricity
Paper is not affected by magnetic fields.
Sea floor spreading / plate tectonics. Also magnetic reversal in the past.
Magnetic Fields - album - was created in 1981-05.
rocks with magnetic fields that point south have
A magnetometer detects magnetic fields.
