A square loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. The loop has total resistance of .8 ohms. It begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of .5 T pointing out of the page. a) while entering the field what is the direction of the induced current as seen from above the plane of...

A very long wire and a square loop of wire lie in the plane of the page as shown. Each side of the square is 15 cm in length, the resistance of the loop is 0.6 Ω, and the near side of the loop is 3 cm from the long wire. The current in the long wire is to the right and is increasing. At the moment, the current in the long wire is 6.5 A. The magnetic flux through...
Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...

For direction questions the choices are: into page, out of page, clockwise, counterclockwise, or no induced field. Letters (m), (n), (q) and (r) have choices: up, down, left, right, into page, out of page, or no induced field. The change in flux is either increasing, decreasing, or constant.
