child holds a butterfly net that is made of a fine mesh net attached to an aluminum rim. The rim is made of a solid pipe with a diameter of 4.00 mm formed into a circle with a radius of 15.0 cm. The child is running around on a 77°F day trying to catch butterflies. At one instant, the net is oriented so that a vector normal to the opening of the net faces due north.
A child holds a butterfly net that is made of a fine mesh net attached to an aluminum rim. The rim is made of a solid pipe with a diameter of 4.00 mm formed into a circle with a radius of 15.0 cm. The child is running around on a 77°F day trying to catch butterflies. At one instant, the net is oriented so that a vector normal to the opening of the net faces due north. The child swings the net in a smooth arc so that 0.80 seconds later, the normal vector points due west. At this location, the Earth’s magnetic field has a magnitude of 49.6 μT and a direction of due north, 63° below the horizontal.T and a direction of due north, 63° below the horizontal.
a) Find the average induced emf in the rim while the net is turning.
b) In the instant before the net finishes its turn, as viewed from the east, the induced current is: Circle one (and show your work): Clockwise or counterclockwise or zero
c) Find the average induced current in the rim while the net is turning. (Hint: you’ll need a table)
