Imagine that the above plate was composed of a piece of wood floating on water with a rod in the center. If a torque were applied to the wood by tilting the rod, part of it would sink below the surface or become depressed, while part of it would rise above the surface or become elevated. The buoyancy of the water would force the part that was under the surface back to the surface. The momentum due to the inertia of the rod attached to the plate would cause the part that was above the water to go below the surface. The rod and the plate would oscillate back and forth in this manner.
Electromagnetic radiation is transmitted through space in a similar manner.
This is similar to how the inertia of the rod attached to the wood plate cause its surface to oscillate above and below the surface of the water. The torque caused by the tilting of the W axis of the fourth spatial dimensions with respect to the axis of length of length width and height of three-dimensional space is responsible for the force we associated with magnetism. Magnetic fields with dissimilar polarities attract because the energy associated with opposite torque subtract and reduce the energy difference between them. Therefore, there will be a net force to bring them together. Magnetic fields with similar polarities repel because the energy associated with similar torques add and increase the energy difference between them.
