प्रश्न
When is the force experienced by a current-carrying straight conductor placed in a uniform magnetic field.
- Maximum
- Minimum
उत्तर
- The force experienced by a current-carrying straight conductor placed in a uniform magnetic field is maximum when the conductor-carrying current is perpendicular to the direction of a uniform magnetic field.
- The force experienced by a current-carrying straight conductor placed in a uniform magnetic field is minimum when the conductor-carrying current is parallel or anti-parallel to the direction of a uniform magnetic field.
