No idea.
#2
Please someone explain me the question. From what I have understood, I think it’s because on connecting wires, it will form a closed loop and will induce an opposing EMF which will induce current in circuit and which will provide an opposing torque to the motion.
#3
Yes, start at instance battery is connected and continue to rise till infinity as current in first will also me maximum at infinity and will keep on increasing till then
#4
Same reason as third, current will be 0 at infinity
#5
Doesn’t inductance only depend on just geometry of solenoid? Then why will it change for ends?
#6
I guess at center as magnetic field lines are denser at center.
#7
The rod will magnetize so field and flux will increase, but answer is (a), (b), (c)
#8
Answer says that (d) is wrong, why? While electron will shift at B, they will collide and produce heat, right?
