A 070-M Radius Cylindrical Region Contains a Uniform Electric Field That

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 0.25 m from the axis has a magnitude of:

A) 0
B) 7.0 * 10^-6 T
C) 2.8 * 10^-5 T
D) 5.4 * 10^-5 T
E) 7.0* 10^-5 T
