Answer:
Magnetic field, B = 0.05 T
Step-by-step explanation:
It is given that,
In magnetic force on a current carrying wire" experiment using the data for force (y-axis, in Newton) versus length in meters, someone obtained a linear curve fit count
y = 0.1 x + 2
Where,
x is in meters
and y is in newtons
Slope of the equation,

Magnetic force is given by,



So, the strength of the magnetic field is 0.05 T. Hence, this is the required solution.
