Question

Q22. the strength of magnetic
field produced by current
carrying solenoid does not
depend on
O no of turns in a coil
o
the strength of current in the
solenoid
O
the nature of core material used in
making solenoid
O reversing the current in the coil​

Answer 1

Answer:

reversing the current in the coil

Answer 2

Answer:

We know that;

By BIot-sawart law,

Where.  

B

 is magnetic field,

I is current

N is number of turns

μ

​  

=Permeability depending on nature of material.

Thus  

B

 is a function of I,N,μ.
