Ive always wondered what happens to the magnetic field of a bar magnet if it is spun at a high velocity around an axis between the poles. Can someone explain.:smile:
The moon is actually orbiting away from earth, future eclipse won't block out as much light. In other words the moons orbit is spiralling away from earth. That is why the moon hasnt collided with us.
The other day I pondered the possibility of harnessing energy from a magnetic field. I was thinkin about windfarms and wondered if a similar process could be created with a fan made of a suitable material in a vacuum. Using the Earths Magnetic field as the Energy Source. Any ideas...
