New block idea: electromagnet and solenoids

essentially a multifunction block:

basically, it emits a field around itself that can either push and/or pull with an adjustable, but relatively weak force; barely enough to lift a 3x3 hollow cube of heavy armor to an acceleration of 10m/s.

Essentially, a gravity generator but for grids exclusively, and if contacted, can stick to non-parent grids. These can then be strengthened with the second blockset: solenoids: effectively, a multi-block structure that rings an electromagnet "core" block to boost its strength by an order of magnitude and double its range, taking the shape of a reinforced copper coil, like pipeworks but more dense.

The electromagnet core should use expensive components like superconductors, computers and detectors, while also being relatively fragile, and if a solenoid ring is broken, it shuts off the whole multiblock structure due to a break in the circuit. it should be at risk of getting subgrids within its range stuck to it, to create interesting engineering challenges that force users to design around them to fully reap the benefits.

This can be used to more easily manipulate grids in 0 g, add protection from debris in shipyards, and also be used for transportation/deployment of vehicles: drone ejection, automatic runways, mag-lev tracks, etc, as well as making a heavier-payload version of railguns, at the cost of range and penetration.

A bonus feature could also be that forcing a rod of heavy armor through a powered solenoid ring will cause an EMP of varying range depending on the acceleration of the rod and how many rings are in the coil.
