Induced Electric Field


<div class="wp-block-create-block-problemblock">The solenoid depicted below has a diameter, ##\Phi## = 10 cm, and initial ##\vec{B}## = 40 mT.  Due to an increasing current, the ##\vec{B}## field increases at 7 ##\frac{mT}{s}##.  Determine the magnitude and direction of the induced electric field at a radius of r = 3 cm within the solenoid.<br /><img src="/old/images/solenoid.gif"  alt="Faraday's Law Solenoid Example Physics "></div>
