Given:
The force on a wire due to a magnetic field is zero.
To find:
The angle between the wire and the magnetic field
Explanation:
For a current-carrying wire of length 'l' and carrying current 'i', the force in the presence of an external magnetic field is,
[tex]F=Bilsin\theta[/tex]The angle between the current direction and the magnetic field is,
[tex]\theta[/tex]So, the force is zero when
[tex]\begin{gathered} sin\theta=0 \\ \theta=0\degree \end{gathered}[/tex]Hence, the angle is zero.
