# Joint Entrance Examination/2000 Screening/Q002 Uniform time varying magnetic field and induced electric field

* Welcome to the Highschool Help Forum!
* The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content.
* The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there.
* If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum
* Lastly, thanks for joining in the site's development process! It matters!

| Original Question by Dharav Here's the question... A uniform but time-varying magnetic field B(t) exists in a circular region of radius a and is directed into the plane of the paper as shown. The magnitude of the induced electric field at point P at a distance r from the centre of the circular region (A) is zero (B) decreases as 1/r (C) increases as r (D) decreases as 1/r^2 Posted by Dharav 09:07, 17 August 2009 (UTC) | What's Up?
