85 N - 40 N = 45 N
And depending on direction the greater force is being pulled towards
Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B = 
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
In order to be considered a vector, a quantity must include Magnitude (A) and Direction (D).
