Answer

Yes, programmable electromagnets that allow you to control various aspects of the magnetic field do exist. These advanced electromagnetic systems offer precise control over the magnetic field's strength, direction, and even dynamic behavior, similar to how you might program a robot to follow specific instructions.

Programmable Magnetic Technologies

Polymagnets

One of the most notable technologies in this field is Polymagnets. These are multi-pole encoded magnets containing small magnetic elements called maxels

. Polymagnets allow for:

Customizable magnetic field patterns
