Detailed Solution
Download Solution PDFCONCEPT:
- When a current-carrying wire is placed in a magnetic field then a force is applied by the magnetic field on the wire. This force is called the magnetic force.
Force on a wire is given by:
\(F = I\;\bar l \times \bar B\)
Where I is the current in the wire, l is the length of the wire and B is the magnetic field
The force on the wire is the cross product of the length vector and magnetic field vector.
EXPLANATION:
- As we can see in the diagrams, the direction of the force depends on both the direction of current in the conductor and the direction of the magnetic field. So option 4 is correct.
