Q-00040526
When is the force on a current-carrying conductor in a magnetic field at its maximum?
1
When the current is parallel to the magnetic field.
2
When the current is at 90 degrees to the magnetic field.
3
When the magnetic field is weak.
4
When there is no current.
Answer and Solution
Answer
B. When the current is at 90 degrees to the magnetic field.
Solution:
The force on the conductor is greatest when the direction of the current is perpendicular (90 degrees) to the direction of the magnetic field, maximizing the interaction.
