Practice 2)
a) Find the force on a straight conductor of length 30 cm carrying a current of 5A in the –az direction through a field B=0.0035ax - 0.0035ay (Wb/m2 ) (ans: -5.25ax – 5.25ay mN)
b) A 18nC point charge has a velocity of 5x106 m/s in the direction (0.60ax + 0.75ay + 0.3az). Determine the force exerted on the charge by the field: i) B= -3ax + 4ay + 6az (mWb/m2 ) (ans: F= 297ax -405ay + 418.5az N) ii) E= -3ax + 4ay + 6az (kV/m) (ans: F= -54ax + 72ay + 108az N)

The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.
