Analysis of nonlinear dynamics in a single magnetic pendulum driven by plate-magnet interaction
Hoang X. Nguyen, Duy V. Nguyen
We analyzed theoretically the nonlinear dynamics of a strong magnetic pendulum consisting of a cylindrical neodymium magnet swinging into a metal plane. The heavy damping of oscill…

On the Electrostatic Interaction between Point Charges due to Dielectrical Shielding
Long T. Nguyen, Kim Tuan Do, Duy V. Nguyen +1
How will the electrostatic interaction between two point charges change if they are shielded from the other by a dielectrical slab? While the physical setting of this electromagnet…
