Question

A straight vertical wire carries a current of 1.35A downward in a region between the poles of a large electromagnet where the field strength is 0.565T and is horizontal. A) What are the direction of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is toward the east? B) What are the magnitude of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is toward the east? C) What are the direction of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is toward the south? D) What are the magnitude of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is toward the south? E) What are the direction of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is 10.0 south of west ? F) What are the magnitude of the magnetic force on a 1.60cm section of this wire if the magnetic-field direction is 10.0 south of west ?

Explanation / Answer

F= ILB

a) (south)

b) force=1.35*1.6*10^-2 *0.565 = 1.2204*10^-2 N

c) west

d) force=1.35*1.6*10^-2 *0.565= 1.2204*10^-2 N

e) 10.0 north of west

f) force=1.35*1.6*10^-2 *0.565=1.2204*10^-2 N
