Detailed Solution
Download Solution PDFConcept:
A solenoid is a wire wound closely in the form of a helix
- when a soft iron rod is inserted inside a magnetic field it magnetizes the iron rod.
- A current-carrying solenoid produces a similar pattern of the magnetic field as a bar magnet.
- The magnet field lines inside the solenoid are in the form of parallel straight lines.
Explanation:
- A current carrying solenoid produces its own magnetic field inside and outside the solenoid
- So, when a soft iron rod is placed inside a solenoid then due to the magnetic field of the solenoid iron rod gets magnetized that's why it increases the magnetic field inside the solenoid
Additional Information
The magnetic field inside a solenoid, B = μ0ni
\(n= \frac{N}{L}\)
Where, μo is the permeability constant = 1.26 × 10−6 T/m,
N is the number of turns in the solenoid,
I is the current passing through the coil,
L is the coil length.
