Answer 2

Answer :-》

• The strength at 0.25 m from any one end of the solenoid will also be L if the intensity of magnetic field produced near one end of solenoid of length 0.5 m is "L".

Explanation :-》

◇ Given,

• Length of solenoid, L = 0.5 m

• Intensity, B = L

◇ To find,

• The strength at 0.25 m from any one end of the solenoid.

◇ We Know That,

• B = µ₀ × N × I / L

Where,

• N = Number of turns

• I = Current

• L = Length of solenoid

• B = Magnetic Field

• µ₀ = Constant = Permeability

So,

• B = µ₀ × N × I / 0.5

=> B = 2 μ N I

As N and I are constant here.

Magnetic field intensity is independent of position, i.e., Positions wont affect the intensity.

So, if position 0.25 m is inside the solenoid by any end of it then the value will be same for B i.e. L.

Note :-

• 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.
