I don't believe there is a special name for that, so you can just use a term similar to what you wrote in the question, for example, "a region with no magnetic field".
the area of magnetic force around a magnet is called the magnetic field

In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
The force that surrounds magnetic objects is called a magnetic field. This field is responsible for the attractive and repulsive forces experienced between magnets and magnetic materials.
The neutral point of a magnetic field is the point in space where the magnetic field intensity is zero. At this point, the magnetic forces acting on a particle will cancel each other out, resulting in no net force. This occurs in regions where magnetic field lines from opposite directions meet and cancel each other.
When a small compass is placed in a magnetic field, the needle of the compass will align itself with the direction of the magnetic field. This is because the needle is magnetized and responds to the magnetic forces in the surrounding area.
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
Magnetic field lines. These lines represent the direction in which a small north magnetic pole would tend to move if placed at any given point in the field.

I'm pretty sure its the 'magnetic field'
