Question

for a current carrying solenoid the term n which has units

Answer 1

Answer:

its unit is per metre because n is the number of turns per unit length. N has no unit but L has metre. in case of N÷L it will b m-1

Answer 2

For a current-carrying solenoid, the formula is

B=μ0nI

• Where,

B is the magnetic induction,

μ0 is the permittivity of free space

n is the number of turns per unit length

I is the current in the solenoid.

Here,

• n refers to the number of turns per unit length
• As we know the solenoid is in form of a circular ring.
• So, the length will become the circumference of the circle.

$n = \frac{number \: of \: turns}{circumference \: of \: the \: circle} = \frac{n}{2\pi \: r}$

Therefore, the SI unit for n is m-¹
