Visitor from Con Ed from a galaxy far away have placed a large (black) ring of wire in the arctic circle around the geographic north pole of the earth. Now they are reducing the earth's magnetic field (but not changing its sign) to induce electric current in their large ring of wire. As seen from far above the north pole...

A grad student is trying to build a velocity selector, shown below.
A grad student is trying to build a velocity selector, shown below. Charged particles will enter the velocity selector from the bottom and only those with the correct velocity v will be able to move in a straight line and leave at the top. The grad student's velocity selector has the electric field E pointing to the left, and the...
