  1. Biot–Savart law - Wikipedia

    In physics, specifically electromagnetism, the Biot–Savart law (/ˈbiːoʊ səˈvɑːr/ or /ˈbjoʊ səˈvɑːr/) is an equation describing the magnetic field generated by an electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current.

  2. Field Equations

    • Beneath the new notation, the magnetic potential field Ω and the magnetic mass m was mentioned here the first time.
    • Therefore Thomas PHIPPS explains this velocity as the velocity of a test charge relative to an observer. Consequently in equation (1.33) the partial derivatives has to be replaced wit...

  4. Electromagnetic Forces and Fields

    • Magnetic fields affect moving charges, and moving charges produce magnetic fields; therefore, the concepts of magnetism and electricity are closely intertwined.
    • The equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle...

    • On the basis of requiring the conformity of electromagnetic field properties and some other field equation properties, associated with its motion, to the laws of
    • We use concepts of intrinsic field and intrinsic velocity. Generally the electromagnetic field has two components, electric and magnetic.

    • Well, if I just have a stationary charge sitting in a magnetic field, nothing really is going to happen, right? Because we know that the force due to a magnetic field is equal to the charge times the cross product of the velocity of the charge and the magnetic field.
