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:
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:
Solving further, we have:
Therefore, the strength of the magnetic field is 0.274 T.
ANSWER:
0.274 T.
