  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...


  3. Magnetic Flux Density

    • The Lorentz Force Equation ties the force due to an external electric field E and an external magnetic flux density B on a charged particle moving at velocity v
    • In general, the magnetic field H and the Magnetic Flux Density B can be used somehwat interchangably, and are related by the permeability...


  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...


  5. In previous papers of the present cycle, in particular [1, 2], we have

    • 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.


  6. Induced current in a wire (video) | Khan Academy | Physics Magnetic forces, magnetic fields, and Faraday's law

    • 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.


  7. Magnetic force on a charge (video) | Khan Academy

    • ...that we have something called an electromagnetic force, once we start learning about Maxwell's equations and relativity and all that.
    • So for example, if the velocity is exactly perpendicular to the magnetic field, then we'll actually get a number. If they're parallel, then the magnetic field has no...


  8. Charged Particle Motion in Electric and Magnetic Fields

    • where is the particle's instantaneous velocity.
    • Let us suppose that the magnetic field is directed along the -axis. As we have just seen, in the frame, the particle's equation of motion reduces to Equation (197), which can be written


  9. ELECTROMAGNETIC INDUCTION | 32.2. The Induced Electric-Field

    • Figure 32.1 shows a rod, made of conducting material, being moved with a velocity v in a uniform magnetic field B. The magnetic force
    • It holds for rods and wires of arbitrary shape moving through arbitrary magnetic fields. Equation (32.5) relates the induced emf to the rate at which the enclosed...

    • Magnets and Magnetic Force. Introduction to magnetism.
    • As long as it's in the magnetic field, the force applied to the particle by the magnetic field is going to be perpendicular to the velocity of the particle.
