The decision can be made only when the 0 premise question is accurately disclosed
In other words, it is desirable to consider that all of the following content is a situation in which the problem is inevitable
The word solenoid appears in the 1st meme
The unit in which this word appears is a magnetic field unit by electric current
This is the only place that appears
2 Suppose that the problem is a magnetic field unit caused by an electric current
It’s more right than
Because the strength of the magnetic field in this unit is proportional to the number of turns of the coil per unit length

(1)Magnetic field current due to circular current
(2)the UAN-S direction of the magnetic field
(3)3 ● Inside the solenoid magnetic field, a uniform magnetic field parallel to the central axis is formed, and outside, a magnetic field similar to the magnetic field produced by a bar magnet is formed. ★ The total length of the unit gillid coil is 2 이ᄂᆞᅳ
(4)a magnetic field of constant strength and direction
(5)① The direction of the magnetic field The direction in which the thumb points when the four fingers of the inner right hand are wrapped in the direction of the current ② The strength of the magnetic field is proportional to the strength of the internal current I and the number of coils winding per unit length is proportional to n
(6)magnetic field due to a solenoid
(7)the direction of the current
(8)the ㄱ of the coil
(9)● Magnetic field by solenoid ◆ Comparison of magnetic fields by solenoid and bar magnet
(10)Observation of magnetic field by electric current in the inquiry data window
(11)Iron around =
3 It is assumed that those who claim to be correct in large numbers are other members of electromagnetic induction
If the question in this unit is correct, it is very correct
But this unit doesn’t have to assume a solenoid
That word doesn’t appear and doesn’t have to appear
4 However, the person who posted the original post put a solenoid in the question unnecessarily in the process of delivering it
Solenoids exist in the problem, but if they were electromagnetic induction units
a lot is right
conclusion
It is precisely right to reasonably infer from known information
But when you reveal the question, it might be the right question
It is more appropriate to support closely with the information to date
a one-line conclusion
It’s a conclusion
