Question
Raised Moved Right Direction of the Current (viewed from above) through the loop before t = 0 s (k) ---Select--- clockwise counterclockwise there is no current at this time (l) ---Select--- clockwise counterclockwise there is no current at this time Direction of the Original Magnetic Field (using the view shown)(the field not created by any current in the loop) (m) ---Select--- up (toward the top of the page) down (toward the bottom of the page) into the page out of the page left right (n) ---Select--- up (toward the top of the page) down (toward the bottom of the page) into the page out of the page left right Change in magnetic flux for loop after t = 0 s (o) ---Select--- increasing decreasing the flux is constant at this time (p) ---Select--- increasing decreasing the flux is constant at this time Direction of the Induced Magnetic Field (using the view shown) after t = 0 s
(at the loop's center) (q) ---Select--- up (toward the top of the page) down (toward the bottom of the page) into the page out of the page left right there is no induced magnetic field at this time (r) ---Select--- up (toward the top of the page) down (toward the bottom of the page) into the page out of the page left right there is no induced magnetic field at this time Direction of the Induced Current (viewed from above) through the loop after t = 0 s (s) ---Select--- clockwise counterclockwise there is no induced current at this time (t) ---Select--- clockwise counterclockwise there is no induced current at this time
Explanation / Answer
k)
before t = 0 , the magnet was not moving . hence there is change in magnetic flux. hence no current in the loop
l)
there is no current at this time
m)
magnetic field by a magnet is from north pole to south pole . hence looking from above , the magnetic field lines seems to be going towards bottom of the page
n)
moving the magnet towards right will not change the direction of magnetic field by the magnet
down (toward the bottom of the page)
o)
the magnet travels towards the loop , hence change in magnetic flux increases
p)
decreasing
since as the magnet is moved right , the magnetic fleild lines passing through the loop will decrease
