Anti-Gravity Boots?

• Does gravity have a magnetic counterpart?

 
• We know that Newton's laws of gravity parallel Couloumb's electric laws; forces acting between currents of electrical charge (Amperes laws) should parallel a force between (currents?) of flowing matter???

 
• Gravity Probe B aims to measure the 'gravitomagnetic' field generated by the Earth spinning in space.  An orbiting Gyroscope (the most precise built to date) will interact with the earth in a spin-spin configuration with error calculated to be less than 1 percent.

 
• Just as a spinning electric charge develops a magnetic field, a spinning mass should develop a similar effect like magnetism.  This has been called 'gravitomagnetism', a force bearly discernable to humans.
