Magnetic field due to currentHard
Question
A uniform magnetic field of 1.5 T exists in a cylindrical region of radius 10.0 cm, it′s direction being parallel to the axis along east to west. A current carrying wire in north south direction passes through this region. The wire intersects the axis and experience a force of 1.2 N downward. If the wire is turned from North South to north east-south west direction, then magnitude and direction of force is -
Options
A.1.2 N upward
B.1.2√2 N downward
C.1.2 N downward
D.
