Question

According to lenz's law the direction of an induced current in a conductor will be that ehich lends to produce which of the following effects? Enhance the effect which produces it. Produce a greater voltage oppose the effect which produces it you are looking at the cross section flat coil carrying a current I. in the counterclockwise direction. What is the direction of the magnitude field at the center of the coil, due to the coil? Out of the page into the page parallel to the page none of the above the direction of the forces on a carrying wire located in an external magnetic field is which of the following ? perpendicular to the current perpendicular to the field both choices a and b are valid none of the above are valid Assume that a uniform magnitude field is directed into this page. If an election is released with an initial velocity directed from the bottom edge to the top edge of the page, which of the following describes the direction of the resultant force acting on the electron? Out of the page to the right to the left into the page if a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field that exerts s force on the management. this force between the management is leaving the loop never The SI unit of magnetic field is the tesla, which is equivalent to a: N/C. A/m. N/(A.m). magnon. None of these.

9.(c)

if we follow the left or right hand rule then according to these laws

10.(c)

11.(c)

Assume, the magnet's North pole faces towards the loop. As the magnet gets closer to the loop, the loop creates induce field to appose the change in the loop caused by the b field of the magnet.as the magnet leaves, the loop creates induce field towards the magnet and the magnets field is pointing away from the loop.
