defence exam ITBP (Telecommunication) Head Constable Mock Test 2024 Physics Electromagnetic Induction and Inductance Mutual Induction
Two long solenoids S1 and S2 of equal length are placed co-axially as shown in the figure. The radius and number of turns per unit length of the solenoid S1 are less than solenoid S2, then the mutual inductance of solenoid S1 will be:
1
More than solenoid S2
2
Less than solenoid S2
3
Equal to the solenoid S2
4
Can't say
