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...

4. Consider a circular loop of wire with a mass m and a radius R. The circular loop is vertical such that gravitational force on the loop points straight down. You may assume this is near the surface of the earth such that the force of gravity has a magnitude FGl mg. The upper half of the circular wire is immersed in a uniform magnetic field B pointing into the page. In the figure below this corresponds to the region...

A long straight wire carrying a current I1 is near a wire loop as shown.
A long straight wire carrying a current I1 is near a wire loop as shown. For each part, determine whether the magnetic flux Φ through the loop due to Ii is into the page, out of the page or zero, and whether the current 12 induced in the loop is clockwise, counterclockwise or zero. a) I1 is constant to the left and the loop is moving toward the wireΦ: into page/out of page/zero I2: clockwise/counterclockwise/zero b) I1 is increasing to the right Φ: into...
