The strength of magnetic field inside a long current carrying straight solenoid is:
The strength of magnetic field inside a long current carrying straight solenoid is:
The correct option is D same at all points
Answer is C
A solenoid is a coil of wire designed to
create a strong magnetic field inside the coil. By wrapping the same
wire many times around a cylinder, the magnetic field due to the wires
can become quite strong. The number of turns refers to the number of
loops the solenoid has. More loops will bring about a stronger magnetic
field.
The magnetic field inside a solenoid is proportional to
both the applied current and the number of turns per unit length. There
is no dependence on the diameter of the solenoid, and the field strength
doesn't depend on the position inside the solenoid, i.e., the field
inside is constant.
The magnetic field is nearly uniform field in
the center, i.e. inside of a long solenoid and the field outside is weak
and divergent.
