Sir: Thanks a lot for your helpful teaching. With all respect, a solenoid is a coil of wire sometimes containing a metal core. So, my question is, should the coil be always insulated from from the core? even if it doesn't have a metal core?

if the turns is 20 turns per centimeter it is still need to convert to meters?
@korzynski
4 жыл бұрын
If the magnetic strength is always in relation to the number of turns per meter, then it seems like increasing the number of turns of wire would have no effect on the strength of the magnet. Assuming the diameter of the wire is unchanged and it can't be coiled any tighter, then increasing the number of turns will increase the length proportionally and they will cancel out. In your example, N=1,500 and l is 5cm, so n=30,000, but if N doubles to 3,000, then l will also double to 10cm and n is still 30,000 and the magnetic force doesn't change. How can this be right?
@shashvatverma5673
4 жыл бұрын
The strength of the field is to do with density. Even if the solenoid is longer, the density of the turns per coil remaining the same will lead to the same magnetic strength. Id think about how magentic strength is not related to the size of the solenoid
@justinorellana6675
2 жыл бұрын
Isn’t what you calculated Mag. Flux density since it’s in Tesla? Also wouldn't you end up with Tesla/Meter as your final units? Why wouldn't you just use B=uIN, since that would give you the total Tesla within the solenoid.

i think we can take any closed loop (any shape) in space as long as we sum up the B//l along it. here by taking a rectangle you can only consider the line within the solenoid coz the other 3 lines are negligible, hence the b field within the solenoids center axis
