The drawing below shows a
copper wire moving vertically at a constant velocity in a
horizontal magnetic field. Which one of the following statements
concerning an induced emf in the wire is true?
a) An emf will be induced in the wire such that both ends of the
wire will have a net negative charge.
b) An emf will be induced in the wire such that both ends of the
wire will have a net positive charge.
C) An emf...

The drawing shows a coil of copper wire that consists of two
semicircles joined by straight sections of wire. In part a the coil
is lying flat on a horizontal surface. The dashed line also lies in
the plane of the horizontal surface. Starting from the orientation
in part a, the smaller semicircle rotates at an angular frequency ω
about the dashed line, until its plane becomes perpendicular to the
horizontal surface, as shown in part b. A uniform magnetic...

A 43.0-cm wire is moving to the right at a speed of 7.90 m/s across two parallel wire rails that are connected on the left side, as shown in the figure. The whole apparatus is immersed in a uniform magnetic field which has a magnitude of 0.750 T and is directed into the screen. What is the emf induced in the wire? induced emf causes a current to flow in the circuit formed by the moving wire and the rails....
