Explanation:
Natural length of a spring is . The spring is streched by
. The resultant energy of the spring is
.
The potential energy of an ideal spring with spring constant and elongation
is given by
.
So, in the current problem, the natural length of the spring is not required to find the spring constant .
∴ The spring constant of the spring =
Answer:
A solenoid field is increased with the increase in the current flow through the coil.
Explanation:
A solenoid is a current carrying coil with a significant number of loops. It works like an electromagnet inside which, a uniform and strong magnetic field is created. The magnetic field outside the solenoid field is nearly zero but not exactly zero.
While experimenting with the solenoid, scientists came to know that the magnetic field generated by the solenoid increases with the increase in the current, flowing through the solenoid.
The magnetic field works strongly around the arena of coil. The field changes its direction only near the ends and gets weak. Else its uniform throughout the loops.
The magnetic field inside the solenoid can be formulated as,
Where,
B = Magnetic field generated by the solenoid
= Constant
I = Current flowing through the loops of the solenoid
