Magnetism
μo - Permeability of free space = 4π X 10-7 (T-m/A)
v - Velocity of the charge Q in m/s
ϴ - Angle between the direction of v and the point P
q - Charge
v - Direction of q
B - Magnetic Field in the perpendicular plane
The ratio of the magnetic field (B) to the magnitizing force (H)
μo - Permeability of vacuum or air = 4π X 10-7 (H/m)
