Effects of Blending Virtual and Real Laboratory Experimentation on Pre-Service Physics Teachers’ Attitudes Toward Physics Electricity and Magnetism Laboratories

Science Education International, 2022
This study examined the effect of blended laboratory experiments on pre-service physics teachers’(PSPTs’) attitudes toward physics laboratories. The research design was a quasi-experimental pre-test and post-test comparing groups.

Animal Magnetism; A Mesmerizing Yet Controversial Past of Healing Sciences

International Journal of Endorsing Health Science Research, 2020
Background: Animal magnetism gained popularity in the 18th century specifically among Europeans and the people from the United States. The Mesmer’s theory on animal magnetism emphasized the presence of invisible natural force in all living organisms i.e.

Direct transition from a disordered to a multiferroic phase on a triangular lattice [PDF]

, 2007
Competing interactions and geometric frustration provide favourable conditions for exotic states of matter. Such competition often causes multiple phase transitions as a function of temperature and can lead to magnetic structures that break inversion ...

Two New Theories for the Current Charge Relativity and the Electric Origin of the Magnetic Force Between Two Filamentary Current Elements

IEEE Access, 2016
This paper presents two new theories and a new current representation to explain the magnetic force between two filamentary current elements as a result of electric force interactions between current charges. The first theory states that a current has an

The geometrical nature and some properties of the capacitance coefficients based on Laplace's Equation

, 2007
The fact that the capacitance coefficients for a set of conductors are geometrical factors is derived in most electricity and magnetism textbooks. We present an alternative derivation based on Laplace's equation that is accessible for an intermediate ...
