A conductor with an active length of 0.4m placed in a uniform magnetic field with an induction of 0.8 T

A conductor with an active length of 0.4m placed in a uniform magnetic field with an induction of 0.8 T is acted upon by a force of 1.6N. determine the current strength in the conductor, provided that it is located perpendicular to the induction lines.

Given:
F = 1.6 N
B = 0.8 T
L = 0.4 m
α = 90 °
Find: I-? AND
Decision :
F = IBLsinα
since the conductor is perpendicular to the lines of the vector
magnetic induction. (α = 90 °).
I = F / BLsinα
I = 1.6 / 0.8 * 0.4 = 160/32 = 5 (A)
Answer: 5 A.
