WebThis is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B. ... I have a magnetic field that is constant, and it's going straight out of the surface of this loop. The magnitude of the magnetic field at any point of the surface is going to be 'B'. What's ... WebThe induced electric field in the coil is constant in magnitude over the cylindrical surface, similar to how Ampere’s law problems with cylinders are solved. Since E → is tangent to the coil, ∮ E → · d l → = ∮ E d l = 2 π r E. When combined with Equation 13.12, this gives. E …
WebThe 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 between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is WebWorked example An aluminium window frame has a width of $40 \mathrm{~cm}$ and length of $73 \mathrm{~cm}$ as shown in the diagram below. The frame is hinged along the vertical edge AC. When the window is closed, the frame is normal to the Earth’s magnetic field with magnetic flux density $1.8 \times 10^{-5} \mathrm{~T}$.
WebThe magnetic moment μ is calculated by the current times the area of the loop or π r 2. μ = I A = ( 2.0 × 10 −3 A) ( π (0.02 m) 2) = 2.5 × 10 −6 A · m 2 The torque and potential energy are calculated by identifying the magnetic moment, magnetic field, and the angle between these two vectors. The calculations of these quantities are: Webvector must be parallel to the magnetic field, which is the case when the plane of the paper is perpendicular to the magnetic field. Because has a magnitude of 1, the magnitude of the maximum flux equals the area multiplied by the magnetic field:. (b) The factor of in equation 20.1 can be zero. Thus, the minimum magnitude of the magnetic flux ...
