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.
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
Same reason as third, current will be 0 at infinity
Doesn’t inductance only depend on just geometry of solenoid? Then why will it change for ends?
I guess at center as magnetic field lines are denser at center.
The rod will magnetize so field and flux will increase, but answer is (a), (b), (c)
Answer says that (d) is wrong, why? While electron will shift at B, they will collide and produce heat, right?
