Question
Considering the three situations below, fill in the tables. This hexagonal loop of wire is in a uniform magnetic field; at t = 0 s, the field begins increasing at a rate of 49 T/s: Direction of the Current through the loop before f = 0 s Direction of the Original Magnetic Field (the field not created by any current in the loop) Change in magnetic flux for loop after t = 0 s Direction of the Induced Magnetic Field after f= 0 s (at the loop's center) Direction of the Induced Current through the loop after t = 0 s (at the loop's center) This rectangular loop of wire is in a uniform magnetic field; at f = 0 s, the field begins decreasing at a rate of 44 T/s: Direction of the Current through the loop before f = 0 s Direction of the Original Magnetic Field (the field not created by any current in the loop) Change in magnetic flux for loop after t=0 s Direction of the Induced Magnetic Field after t = 0 s (at the loop's center) Direction of the Induced Current through the loop after t = 0 s 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 Direction of the Current through the loop before t= 0 s Direction of the Original Magnetic Field (the field not created by any current in the loop) Change in magnetic flux for loop after t= 0 s Direction of the Induced Magnetic Field after f=0 s (at the loop's center) Direction of the Induced Current through the loop after t = 0 s II: This rectangular loop of wire is in a uniform magnetic field; at t = 0 s, the field begins decreasing at a rate of 44 T/s: Direction of the Current through the loop before f = 0 s Direction of the Original Magnetic Field (the field not created by any current in the loop) Change in magnetic flux for loop after t= 0 s Direction of the Induced Magnetic Field after t = 0 s (at the loop's center) Direction of the Induced Current through the loop after t = 0 s II: 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 left Direction of the Current (viewed from above) through the loop before t = 0 s Direction of the Original Magnetic Field using the view shown) (the field not created by any current in the loop) Change in magnetic flux for loop after f= 0 s Direction of the Induced Magnetic Field (using the view shown) after t = 0 s (at the loop's center) Direction of the Induced Current (viewed from above) through the loop after t = 0 s III: 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 left. Direction of the Current (viewed from above) through the loop before t = 0 s Direction of the Original Magnetic Field using the view shown) (the field not created by any current in the loop) Change in magnetic flux for loop after f= 0 s Direction of the Induced Magnetic Field (using the view shown) after t = 0s (at the loop's center) Direction of the Induced Current (viewed from above) through the loop after t = 0 sExplanation / Answer
Q1
a) no current before t= 0 so no direction before t= 0
b) into the plane
c) flux = d(phi) /dt = d(BA) / dt = A *dB/dt show me your option we can't decide here what is this question asking aabout
d) by lenz's law it will oppose this incresing magnetic field so
it will be opposite to this magnetic field so
answer = out of the paper plane
e) to produce magnetic field out of the paper palen B current should be anti clock wise by right hand rule
Q2
f ) no direction same logic here
g) out of the paper plane
h) show me your option
i) same logic here so answer = out of the paper plane
j) because external magnetic field decreasing so by Lenz's law current will produce in loop to increase the magnetic field so answer = > anti clockwise
Q3
a) same logic no direction
b) down in south
c)Plz show me you option
d) loop should behve like North pole by lenz's law so direction from the top
= upward in north
e) induced current = anti clockwise
