A solenoid used to produce magnetic fields for research purposes is 2.1 m long, with an inner radius of 28 cm and 1300 turns of

wire. When running, the solenoid produced a field of 1.3 T in the center. Given this, how large a current does it carry?

Answer:

1671 A

Explanation:

With a logical assumption that magnetic permeability of vacuum would be used,

the magnetic field at the centre of a solenoid is given by

B = μ₀I (N/L)

Some textbooks use turn density, n = (N/L)

Either ways,

B = 1.3 T

μ₀ = (4π × 10⁻⁷) H/m

I = ?

N = 1300 turns

L = 2.1 m

I = (BL/μ₀N)

I = (1.3×2.1) ÷ (4π × 10⁻⁷ × 1300)

I = 1671 A

Hope this Helps!!!

The moon's surface gravity is one-sixth that of the earth. Calculate the weight on the moon of an object that has a mass of 24 k
ad-work [718]
When we say "<span>The moon's surface gravity is one-sixth that of the earth.",
we mean that the acceleration of gravity on the Moon's surface is 1/6 of
the acceleration of gravity on the Earth's surface.

The acceleration of gravity is (9.8 m/s</span>²) on the Earth's surface, so
<span>it would be (9.8/6 m/s</span>²) on the Moon's surface.
<span>
The weight of any object, right now, is

(object's mass) </span>· (acceleration of gravity where the object is located now) .
<span>
If the object's mass is 24 kg and the object is on the Moon right now,
then its weight is 

(24 kg) </span>· (9.8/6 m/s²)

= (24 · 9.8 / 6) kg-m/s²

= 39.2 Newtons
