A field of electromagnetic effect. Obviously.
>>>>Any field effect, electric, magnetic, electromagnetic, whatever, falls off rapidly, you know, following the *inverse square law*. That’s why, even with a powerful magnet, if you remove the magnet from the steel cover and withdraw it an inch or two there is no more magnetic attraction, pull. You can even feel it stop. At some point the Earth’s magnetic field has more of an effect. Obviously.
