A 0.70-m radius cylindrical region contains a uniform electric field that is parallel to the axis and is increasing at the rate 5.0 * 10¹² V/m . s. The magnetic field at a point 1.2 m from the axis has a magnitude of:

Question

Quizplus · Accepted Answer

The magnetic field at a distance from the axis of a cylindrical region with a changing electric field can be calculated using Ampère's law with Maxwell's addition. The displacement current density is proportional to the rate of change of the electric field. Using the formula B = (μ₀ε₀r/2) * (dE/dt) for r > R, where R is the radius of the cylinder, we find the magnetic field at 1.2 m from the axis.
