# Conceptual question about (GEM forces)

• Herjap

#### Herjap

please note- (GEM forces) stand for gravitational or electric forces.

Under normal circumstances, we are not aware of the gravitational or electric forces between two everyday objects.
Is this so because of the relative mass of these objects are very small in magnitude, when compared to larger objects like planets...

This would be true for gravitational force. Why do you think gravitational and electric forces should go together in this?
For electric forces the mass is not relevant.

Yes, therefore mass is only relevant to gravitational forces. But I am confused why we are not aware of the electric forces between two everyday objects

Because most everyday objects are electrically neutral. They have equal numbers of positive and negative charges so that overall they are neutral, have no net charge.
The effect of electric forces becomes visible of you somehow produce a (small) imbalance between these charges and the object becomes "charged".

## 1. What are GEM forces?

GEM forces, also known as Generalized Exchange-Mixing forces, refer to the forces that result from the interactions between the electron wavefunctions in a solid material. These forces play a crucial role in determining the electronic and magnetic properties of materials.

## 2. How do GEM forces affect the properties of materials?

GEM forces can significantly influence the electronic and magnetic properties of materials. For example, they can affect the band structure and electronic conductivity of a material, as well as its magnetic ordering and response to external magnetic fields.

## 3. What factors determine the strength of GEM forces?

The strength of GEM forces depends on various factors, such as the electronic structure of the material, the distance between atoms, and the orientation of their spins. Additionally, the type of bonding (e.g., covalent, metallic, or van der Waals) also plays a role in determining the strength of GEM forces.

## 4. Can GEM forces be manipulated or controlled?

Yes, GEM forces can be manipulated and controlled through various methods, such as applying external electric or magnetic fields, changing the temperature, or altering the composition of the material. This allows for the tuning of a material's electronic and magnetic properties for specific applications.

## 5. What are some real-world applications of GEM forces?

GEM forces have numerous applications in various fields, such as electronics, spintronics, and materials science. They are essential for the development of new electronic devices, such as transistors and memory storage devices, as well as for understanding and designing new magnetic materials for data storage and sensing applications.
