| 11. Two solenoids P and Q have length and the total number of turns in the ratio of 1:2. What is the ratio of the magnetic field inside the two solenoids due to the same current? |
| |
| Suggested solution: |
| |
| Let N1 and L1 denote the total number of turns and length of the solenoid P. The corresponding quantities for the solenoid Q are N2 and L2. |
| |
| Given: |
| |
| |
 |
| |
| Let n1 and n2 denote the number of turns per unit length in the solenoid P and Q respectively, Obviously |
| |
 |
| |
 |
| |
| Since n and I are same, B will be same. Therefore B1 / B2 = 1 |
