Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too high

Motional EMF Below is a rectangle that is being pulled into a magnetic field as shown. The rectangle has a height of h = 0.400 m and is being pulled to the right with a velocity of v = 188.0 m/s. This magnetic field starts where shown, so the left most side of the rectangle has no magnetic field. There is 1 loop with a total resistance of R = 15.40 Ohms. The magnetic field has a magnitude of B = 34.0 mT. That means as the loop moves to the right, the magnetic flux inside the loop is increasing. Magnetic Field (out of the page) Direction of velocity What is the induced current within the wire in this system? (Use a negative sign for clockwise current) Make sure to give your answer with appropriate significant figures and remember that you are looking for a magnitude. Your Answer: Answer units Height
