Magnetic Lens Made of a Single Solenoid for Controlling Bending of Two-Dimensional Ion Beam
Ardi Khalifah, Riri Murniati, Mikrajuddin Abdullah
The magnetic field inside an ideal solenoid cavity with an arbitrary cross-section is always constant, while it is always zero outside the solenoid. We can make a solenoid lens tha…
Introducing Cashless Transaction Index based on the Effective Medium Approximation
Mikrajuddin Abdullah
The effective medium approximation (EMA) method is commonly used to estimate the effective conductivity development in composites containing two types of materials: conductors and…
Physics of Bamboo Rifle
Ardi Khalifah, Mikrajuddin Abdullah
We conducted simple experiments and derived physics equations to explain the working principle of a bamboo rifle. This toy is often played by children in many places that have bamb…
Slope of Dry Granular Materials Surface is Generally Curved
Fathan Akbar, Elfi Yuliza, Nadya Amalia +2
As if it has become a consensus that the slope of the granular heap is straight, and from that, an angle of repose is defined. However, closer inspection shows that the slopes are…
Coulomb-like Model for International Trade Flow and Derivation of Distribution Function for Trade Flow Strength
Mikrajuddin Abdullah
To describe international trade flows, we propose the coulomb force formulation, in which the magnitude of the charge represents gross domestic product (GDP) and the distance betwe…
Bending of Spaghetti Beams and Columns Exposed to Hot Steam Reveals Several Physical Properties of the Spaghetti
Fathan Akbar, Mikrajuddin Abdullah
In this paper, we show that bending of spaghetti beams and columns exposed to hot steam reveals the time evolution of young modulus, the diffusion coefficient of water molecules pe…
