Gravity and magnetism are not inventions, they are natural phenomena.
Magnetism and Gravity.
Gravity, magnetism, and electrostatic.
It doesn't. Magnetism is a force in nature and gravity is a wholly desperate force.
The force of Gravity. I thought it was magnetism
Gravity is strictly an attractive force.
Gravity. Magnetism is a fairly short-range force, but gravity goes on forever.
Gravity,Magnetism,Strong nuclear force,Weak nuclear force
There are only two forces that act at a distance:gravity, andelectromagnetism.Magnetic fields are sometimes referred to as a third force, however magnetism and electrostatic forces are both examples the electromagnetic force.
Electricity is not a force. The others are.
Magnetism , gravity, and electricity
Friction.
Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass
