What is the work required to move a charge along an equipotential? The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to […]

What are the basic principles of scientific thinking?
What are the basic principles of scientific thinking? The Six Principles of Scientific Thinking. For a claim to be meaningful, it must in principle be falsifiable, that is, capable of being disproven. For Example: The claim that “all human beings have invisible souls” isn’t necessarily wrong but it is unfalsifiable because no evidence could conceivably […]

What does negative permeability mean?
What does negative permeability mean? Negative magnetic permeability is when a material, in response to an imposed magnetic field, forms a magnetic dipole in the opposite direction to the imposed field. As regards PLASMA in a Magnetic Field the particles gyration results in a magnetic moment countering the external field. Therefore plasma is diamagnetic. Can […]
How current is measured?
How current is measured? Current is measured in Amperes (usually just referred to as “Amps”). An ampere is defined as 6.241*10^18 electrons (1 Coulomb) per second passing through a point in a circuit. Amps are represented in equations by the letter “I”. This is analogous to an increase in voltage that causes an increase in […]
