For a straight conductor of length

L

carrying current

I

in a uniform magnetic field

B

, the magnetic force on the conductor is maximum when the conductor is (a) inclined at

45^\circ

to the magnetic field (b) perpendicular to the magnetic field (

\theta = 90^\circ

) (c) parallel to the magnetic field (

\theta = 0^\circ

) (d) independent of the angle with the magnetic field
