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...
Two parallel lengths of wire are separated by 10 cm and connected at the left edge by a 160 resistor. A conducting bar rests on the wires, perpendicular to both, and is pulled to the right at 12 m/s. A magnetic field of 2.2 T points into the page through the coll, such that the magnetic field is perpendicular to the plane of the loop. a) What is the emf induced in the loop? b) What is the current in the loop?c)...

(b) What is the average emf if the sides of the loop were only 20cm?
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 0.8 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 0.5 T pointing into the page. Finally it leaves the field. 21) While entering the field what is the direction of the induced current as seen from above...
