MCQ
In a current carrying long solenoid, the field produced does not depend upon
- ANumber of turns per unit length
- BCurrent flowing
- ✓Radius of the solenoid
- DAll of the above three
✓
Answer
Correct option: C.
Radius of the solenoid
c
The magnetic field at the center of solenoid is given as:
The magnetic field at the center of solenoid is given as:
$B =\mu_0 ni$
where $n$ is number of turns per unit length $=\frac{ N }{ l }$
$i$ is the current through the solenoid.
So, the magnetic field does not depend on the radius of the solenoid.
