The magnetic field at a point 1.2 m from the axis has a magnitude of 7.0 × 10^–6 T

<h3>Further explanation </h3>

Maxwell's equation is a set of coupled partial differential equations that together with the Lorentz force law form the classical electromagnetism, classical optics, and electric circuits.

Integral form in the absence of magnetic or polarizable media are Gauss' law for electricity, Gauss' law for magnetism, Faraday's law of induction, Ampere's law

A 0.70 m radius cylindrical region contains a uniform electric field that is parallel to the axis and is increasing at the rate $5.0* 10^{12} v/m.s$ The magnetic field at a point 1.2 m from the axis has a magnitude of?

The Maxwell’s law of induction is as follows. Consider the charging of our circular plate capacitor , B field also induced at point 2. When capacitor stops charging B field disappears.

By using the Maxwell’s law of induction for a circle of radius r.

$2\pi rB = \epsilon_{0}\mu_{0}\pi r^2 \frac{dE}{dt} , B = \frac{1}{2} \epsilon_{0}\mu_{0}r\frac{dE}{dt} = 7*10^{-6}T$

Magnetic fields are effects that are being produced by electric currents that are present in a material. It is characterized by both magnitude and direction so it should be a vector quantity. Magnetic field is represented by B and is proportional to the current that is passing through. It is equal to the product of a constant, uo, and the current divided by the product of 2(pi) and the distance from the wire. Base from the problem statement, there was no value of current mentioned. Therefore, the magnetic field would be zero. No magnetic fields are produced when current is zero.
