Webquantity H,andB is called the magnetic induction.) In terms of the field, the magnetic force on i dl is Equation (3.5) involves the vector cross product. The force is perpendicular to both the current element and magnetic field vector. An expression for the total electric and magnetic forces on a single particle is required to treat beam dynamics. WebThe answer is that the source of the work is an electric field E → that is induced in the wires. The work done by E → in moving a unit charge completely around a circuit is the induced emf ε; that is, ε = ∮ E → · d l →, 13.9. where ∮ represents the line integral around the circuit. Faraday’s law can be written in terms of the ... computer shops in grantham
