I'd really appreciate some help with the following questions.(adsbygoogle = window.adsbygoogle || []).push({});

Q1) What is the direct of the induced current in the circular loop due to the current shown in each part of the following fig?

Have attached pics of 2 questions. The one on top has I increasing and one on the bottom has I decreasing.

HOw do I go about getting it?

For the first one, I get the external magnetic field to be going downward ( intot he paper ) but then how do I find the induced magnetic field since the decreasing current does not tell me anything about the flux?

q2) A 10.2 cm diameter wire coil is initially oriented so that its plane is perpendicular to a magnet field of .63T pointing up. During the course of .15s, the field is changed to one of .25T pointing down. What is the average induced EMF in the coil?

I did the followng:-( [(.63)(3.14)(.102/2)^2] - [(.25)(3.14)(.102/2)^2]) / (.15) and got .021V. Is this correct?

Thanks
