Knowledge and Skills Statement

Science concepts. The student knows the nature of forces in the physical world.

a component of electromagnetic force that is produced by static (non-moving) electric charges; an attraction or repulsion of particles or objects due to their electric charge

an area around an object where non-contact forces such as gravitational, electric, or magnetic forces can impact the behavior of other objects that enter the field

a push or pull between two objects

a component of electromagnetic force that is a non-contact force produced by moving electric charges, whether in atoms or in wire

Research

Hart, David A. "The Influence of Magnetic Fields, Including the Planetary Magnetic Field, on Complex Life Forms: How Do Biological Systems Function in This Field and in Electromagnetic Fields?" Biophysica 4, no.1 (2024): 1-21. https://doi.org/10.3390/biophysica4010001

Summary:  Homo sapiens evolved a neurological system, a neuromuscular system, and a cardiovascular system that developed electromagnetic fields as part of their functioning. All of these could be impacted by magnetic fields. In addition, many proteins and physiologic processes utilize iron ions, which exhibit magnetic properties. Thus, complex organisms, such as humans, generate magnetic fields, contain significant quantities of iron ions, and respond to exogenous static and electromagnetic fields.

"Effects of High Voltage Electrostatic Field and Weak Magnetic Field Assisted Refrigeration on Preservation of Spinach." Journal of Food Measurement & Characterization 17, no. 6 (2023): 6484-6502. https://doi.org/10.1007/s11694-023-02119-9

Summary:  Weak magnetic feld and high voltage electrostatic feld-assisted refrigeration is a new physical method of food preservation, which not only does not contaminate food but also avoids adverse efects on the human body. The efect of spinach preservation under diferent magnetic feld strength and electric feld strength assisted refrigeration was investigated, with conventional refrigerator preservation being used as a control.
