Question

Problem 20.25 Part A A straight vertical wire carries a current of 1.35 A downward in a region between the poles of a large electromagnet where the field strength is 0.580 T and is horizontal. What are the direction of the magnetic force on a 1.40 cm section of this wire if the magnetic-field direction is toward the east?

Explanation / Answer

By using equation

F= ILB

a) (south)

b) force=1.35*1.4*10^-2 *0.580 = 1.096*10^-2 N

c) west

d) force=1.35*1.4*10^-2 *0.580= 1.096*10^-2 N
