I think false I don't know if I right but I hoped this help

Answer:</h2>
<em>1.33 x 10⁻ ⁴ T outwards.</em>
<em></em>
<h2>
Explanation:</h2>
The equation for the magnetic force (F) on a wire whose length is L and carrying a current I in a magnetic field (B) that is uniform is given by;
F = ILB sin θ ---------------------(i)
Where;
θ = angle between the direction of the current and that of the magnetic field.
From the question,
F = 4.0 × 10⁻² N
I = 12A
L = 25m
θ = 90°
<em>Substitute these values into equation(i) and solve as follows;</em>
4.0 × 10⁻² = 12 x 25 x B x sin 90°
4.0 × 10⁻² = 300 x B x 1
4.0 × 10⁻² = 300B
0.04 = 300B
B = 
B = 0.000133
B = 1.33 x 10⁻ ⁴ T
To get the direction of the magnetic field, the right-hand rule is used.
If the right hand fingers are positioned in the correct order specified by the right hand rule, then it would be seen that the magnetic field is directed outwards.
Therefore, the magnitude and direction of the magnetic field at this location is <em>1.33 x 10⁻ ⁴ T outwards.</em>
Well i would feel i am moving i also would be scared if i didnt know i was moving even with my eyes closed
The course to be likely taken by a mechanical engineer in college is agriculture operations (option A).
<h3>What is engineering?</h3>
Engineering is application of mathematics and the physical sciences to the needs of humanity and the development of technology.
Mechanical engineering is a subfield of engineering concerned with designing and building machines and mechanical systems.
A mechanical engineer is an individual who specialises in the field of mechanical engineering. This means that a mechanical engineer is expected to be vast in the knowledge of designing and building machines for operations in other fields.
One of those fields that a mechanical engineer can build or design machine for is agriculture. Therefore, agriculture operations is the most likely course to be taken by a mechanical engineer in college.
