answer :
force is called the magnetic force of repulsion, and it happens when two magnets have the same poles (either both north or both south) and they push away from each other.
When all the domains in a material are aligned in the same direction, the material becomes strongly magnetized.
explanation :
magnetic domains in the rings were stable and strong enough to resist the force of gravity.
In the case of the levitating rings, the magnetic domains were aligned in such a way that they created a strong magnetic field, which allowed the rings to levitate in mid-air.
tiny regions within ferro magnetic material that have their own magnetic fields are called magnetic domains.
Magnetic domains in the rings refer to the tiny regions within the ring's ferro magnetic material that have their own magnetic fields.
