Question
Raised Moved Right Direction of the Current (viewed from above) through the loop before t = 0 s (k) ---Select---clockwisecounterclockwisethere is no current at this time (l) ______ 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 pageout of the pageleftright (n) ______ Change in magnetic flux for loop after t = 0 s (o) ---Select---increasingdecreasingthe flux is constant at this time (p) ______ 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 pageout of the pageleftrightthere is no induced magnetic field at this time (r) ______ Direction of the Induced Current (viewed from above) through the loop after t = 0 s (s) ---Select---clockwisecounterclockwisethere is no induced current at this time (t) ______ The figure shows a side view of a loop of wire with a bar magnet near but below the loop. The bar magnet's south pole is aimed up (towards the loop). At t = 0 s, the magnet is moved; it is either raised or moved right.
Explanation / Answer
A: At time 0, there is NO current when raised or moved to the left B: The original magnetic field is down in both cases C: After t=0, the flux is increasing as you move the magnet upwards (More field flowing through the loop) and is decreasing as you move it left (Less field moving through the loop) D: The induced field is upwards when you raise the bar magnet (Induced field goes in the OPPOSITE direction of the original field as flux increases) and the induced field is down when you move the bar magnet to the left (induced field goes in the SAME direction of the original field as flux decreases) E: Since the induced field is going up when the bar magnet is raised, the right hand rule shows that the current is flowing counter-clockwise. When you move it left, flux decreases so the field is down. The right hand rule shows that this current will be clockwise
