A long, straight wire, carrying a current of 200 A, runs through
a cubical wooden box, entering and leaving through holes in the
centers of opposite faces (see the figure (Figure 1) ). The length
of each side of the box is 20.0 cm. Consider an element

A beam of photons (q = +1.6 x 10^-19 C) is moving with various speeds in the positive x direction (to the right). It enters a region where there is a uniform magnetic field of magnitude 0.25T pointing in the negative z direction (into the page). a) The protons feel a force due to this magnetic field. Explain why, and...
