Force on a moving charge

A moving charge in an electric field experiences a force that is proportional to the strength of the electric field and the magnitude of the charge. The direction of the force is given by the direction of the electric field and the sign of the charge. The mathematical expression for the force on a moving…

Ampere’s law

Ampere’s law is a fundamental law in electromagnetism that relates the magnetic field to the electric current that produces it. It states that the magnetic field around a closed loop is proportional to the electric current passing through the loop. Mathematically, Ampere’s law can be expressed as: ∮B·dl = μ0I where: Ampere’s law is an…
