180o domain wall between two domains is known as Bloch wall. The Bloch wall energy is competition between exchange energy and anisotropy energy within the interface of two domains. The exchange energy in a ferromagnetic material is a minimum only when adjacent spins are parallel. While anisotropy energy will be minimum when the spins remain parallel to the easy axis.
Bloch wall energy will be minimum of exchange energy and anisotropy energy
Mathematically, the Bloch wall energy for an uniaxial anisotropic material will be
(sigma)exch+(sigma)anis=(JS2 pi2)/Na2+KuNa
where J is exchange stiffness, N is number of atoms within the wall, a is distance between two adjacent atoms, Ku is the uniaxial anisotropy constant
the minimum of this energy terms will be
(sigma)dw~2pi(AKu)1/2
where A is the exchange stiffness constant. it is the energy of the Bloch wall in uniaxial ferromagnetic material. (read more in Cullity's Book)
The energy in a wall plug is electrical energy, which typically comes from the electricity grid. When a device is plugged into the wall socket, this electrical energy is converted to power the device and perform its intended function.
When a ball hits a wall, some of its kinetic energy is transformed into sound energy and heat due to the impact. Additionally, a small amount of the kinetic energy may be absorbed by the wall as potential energy if the wall temporarily compresses upon impact.
No, a picture hanging on the wall does not have kinetic energy because it is not in motion. Kinetic energy is the energy possessed by an object due to its motion.
The energy transfer for a lamp plugged into the wall involves the electrical energy from the power source (wall outlet) being converted into light energy by the lamp's bulb. The electrical energy powers the lamp's circuit, which then produces light as a form of energy.
Electric energy is used for a wall socket, which comes from the electrical grid and is converted into usable electricity to power devices and appliances.
