A solenoid has a core of material with relative permeability 400. The windings of the solenoid are insulated from the core and carry a current 2 A and having number of turns 1000 per meter. By considering the situation, choose the incorrect pair.
A
Magnetic intensity (H) 
B
Magnetic field 
C
Magnetisation (I) 
D
Magnetizing current (I m ) 
Text Solution
Verified by ExpertsThe correct answer is:
C
Number of turn 
Current
Number of turn (Current + Magnetic current)
Putting the values, 
and 
, we get magnetising current
