Define magnitude and direction `vecB` in a magnetic field.

Magnetic moments of two small magnets are 0.108A.m^(2) and 0.192A.m^(2) . The magnets are placed perpendicular to each other on a horizontal plane . They are at distances of 30 cm and 40 cm , respectively , from the junction point of their axes . Determine the magnitude and direction of the resultant magnetic field at this junction point .

Define flux in a magnetic field.

A long wire carries a current of 90 A in the east to west direction. What is the magnitude and direction of magnetic field due to the current I.5m below the line?

Define the unit of magnetic field vecB .

Statement : I Neither the magnetic field vector vecB nor the magnetic intensity vector vecH of a magnetic field depend on the nature of the medium. Statement : II If the magnetic permeability of a medium is mu then vecH=(1)/(mu)vecB
