L = μoμrN 2I A l. It is clear that self inductance of solenoid depends upon the following factors: (1) On relative permeability of material inside the solenoid: If a soft iron core placed inside the solenoid, the magnetic flux linked with the solenoid increased hence, self inductance of the solenoid will also increases.
Derive expression for the self inductance of a solenoid. What factors affect it? Solution. Verified by Toppr. Self Inductance of a Current Carrying Solenoid: Consider a solenoid of radius r metre, length l metre, having total number of turns N and carrying a current I ampere. The magnetic field produced on its axis inside the solenoid is.
A wire of fixed length is wound on a solenoid of length l and radius r. Its self inductance is found to be L. Now, if same wire is wound on a solenoid of length l 2 and radius r 2, then self inductance will be
The self-inductance of another Solenoid of 50 turns (with the same length and cross-sectional area) with a core having relative permeability 500 is. The number of turns in an air core solenoid of length 25 cm and radius 4 cm is 100. Its self inductance will be. An air core solenoid has 1000 turns and is one metre long.
The self-inductance of an air core solenoid of 100 turns is 1 m H. The self-inductance of another Solenoid of 50 turns (with the same length and cross-sectional area) with a core having relative permeability 500 is
Solution. In expression for the self-inductance of a long solenoid. Consider a solenoid of N turns with length l and area of cross section A. It carries a current I. If B is the magnetic field at any point inside the solenoid, then Magnetic flux per turn = B × area of each turn. Hence, the total magnetic flux (ϕ) linked with the solenoid is ...
Self-inductance of a coil is defined as the phenomenon due to which an emf is induced in a coil when the magnetic flux of coil , linked with the coil changes or current in coil changes . Its S.I. unit is H e n r y (H).
A solenoid of length 1 m, area of cross-section 4.0 c m 2 and having 4000 turns is placed inside another solenoid of 2000 turns having a cross-sectional area 6 c m 2 and length 2 m. The mutual inductance between the solenoids is x π × 10 − 5 H .
The self-inductance of an air core solenoid of 100 turns is 1 m H. The self-inductance of another Solenoid of 50 turns (with the same length and cross-sectional area) with a core having relative permeability 500 is
Establish expression for self inductance of a long solenoid. Self inductance: When the current is passed through a coil, the magnetic flux linked with the coil is directly proportional is the current. Where L is constant, its value depends upon shape and size of the coil meidum and number of turns. It is called self inductance or coefficient of ...
