Given:

• Number of turns = 10400 turns

,

• Current = 21.0 A

Let's find the strength of the magnetic field.

To find the strength in the magnetic field, apply the formula:


B=\mu_onI

Where:

• B is the magnetic field

,

• μ₀ is the permeability of free space.

,

• n is the number of turns.

,

• I is the current.

Thus, we have:


B=(4\pi*10^(-7))*10400*21

Solving further, we have:


B=0.274\text{ T}

Therefore, the strength of the magnetic field is 0.274 T.

ANSWER:

0.274 T.
