A rod when suspended in a magnetic field stays in east-west direction. Can we be sure that the field is in the east-west direction? Can it be in the north-south direction?

A current carrying wire is placed along east and west in a magnetic field directed north wards. If the current in the wire is directed east wards, the direction of force on the wire is

A uniform magnetic field of 1.5 T exists in a cylindrical region of radius 10.0 cm, its direction parallel to the axis is along east to west. A wire carrying current of 7.0 A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if, a. the wire intersects the axis, the wire is turned from N S to north east-south west direction. c. the wire in the N-S direction is lowered from the axis by a distance 6.0 cm.

A uniform magnetic field of 1*5T is in cylindrical region of radius 10*0cm with its direction parallel to the axis along east to west. A wire carrying current of 7*0A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if (a) the wire intersects the axes, (b) the wire is turned from N-S to north east-south west direction, (c) the wire in the N-S direction is lowered from the axis by a distance 6*0cm ?
