A study published in The Astrophysical Journal Letters, introduces a newly defined "filament channel" function. This new ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: 2 A flows through a 50 cm wire. Calculate the force acting on the wire when it is placed ...

Earlier, it was claimed that the forces that generate Earth’s magnetic field are constantly changing; the field itself is also in continual flux, its strength waxing and waning over time.
