Exercise 5.4 a horizontal wire with a mass per unit
length of 0.2 kg/m camies a current of 4 a in the
tax-direction. if the wire is placed in a uniform magnetic
flux density b, what should the direction and minimum
magnitude of b be in order to magnetically lift the wire
vertically upward? (hint: the acceleration due to gravity
is g=-19.8 m/s.)

ans. b = 90.49 t.
