A) directly proportional to its length
B) directly proportional to the current
C) inversely proportional to total number of turns
D) inversely proportional to current
Correct Answer: B
Solution :
Magnetic field produced due to a solenoid is \[B={{\mu }_{0}}ni\] \[\therefore \] \[B\propto i\] Magnetic field is directly proportional to current flowing i.
