Q:How do you get the screwdriver to restore the magnetic force?

Force (magnetic) is the force of the magnetic field in which the magnets and currents are placed. Magnetic force is the electromagnetic field, the speed of the electromagnetic field is the speed of light, and the speed of the action of the magnetic force is also the speed of light. As it is not yet clear about its nature, it is not known whether a magnetic black hole exists, and no strong magnetic field has been observed at present. And if the magnetic force does not bend spacetime, it does not form a magnetic black hole.
