I love how the mass of an objects along with space and time create magnetism moreover an magnetic field is a byproduct, so if used correctly generates an electric field.
Try this one day at the beach (try a riverside if not) pick up two dark black rocks and put 1 in each hand. Then rotate both rocks around each other simultaneously after 15 to 20 seconds swiftly, then slowly connect the rocks together you will feel them repelling this is the ultimate example of magnetism.
