How do you put a magnetic charge in a material?
First you'll have to 'invent' a magnetic charge. And, according to Maxwells Equations, there is no such thing nor can there be such a thing. Magnetic poles always come in pairs. A north and a south. And they are never found in isolation. HTH ? Doug
the springs might be too weak for the weight, allowing the cr to sit lower.
They sell rubber spacer blocks that go between the coils in the spring. This keeps it higher.
