The direction of current in a solenoid depends on the direction of magnetic field’. Do you agree with this statement? Showthe pa
ttern of magnetic field lines of a solenoid through which a steady current flows. What does the pattern of field lines insidethe solenoid indicate
1 answer:
Answer:
1) Yes the direction of the magnetic field is found based on Fleming's Right Hand Rule
2) The pattern indicates the direction of the magnetic force field lines
Explanation:
1) The solenoid is the is the coil of electric conductor that when it carries an electric current produces a magnetic field
According to Fleming's Right Hand Rule, the direction of the magnetic field produced by a solenoid, depends on the direction of the current such that when the direction of the conventional current is in the direction of the wrapped fingers, the thumb points in the direction of the magnetic field which is North N.
2) The pattern of field lines inside the solenoid indicates the direction of the generated magnetic field moving from left to right within the solenoid as the electric current moves around in the direction shown in the diagram.

Answer:
Explanation:
radius of the solenoid, r = 0.05 m
length of the solenoid, l = 0.39 m
Magnetic field of the solenoid, B = 2 x 10^-5 T
Number of turns, N = 200
The magnetic field of the solenoid is given by
where, i be the current and n be the number of turns per unit length
n = N / l = 200 / 0.39 = 512.8
i = 0.031 A
