Question
Which of the following factors affect the strength of force experienced by a current-carrying conductor in a uniform magnetic field?
- Magnetic field strength
- Magnitude of current in a conductor
- Length of the conductor within the magnetic field
- All the above
Hint:
The force on a current carrying conductor placed in a magnetic field is given by the Flemings left hand rule.
F = B I L
The correct answer is: All the above
The force on a current carrying conductor placed in a magnetic field is given by the Flemings left hand rule.
F = B I L
Where F is the force on the conductor
B is the magnitude of the uniform magnetic field
I is the current in the conductor
L is the Length of the current carrying wire
Therefore from the above formula, force is directly proportional to the magnitude of the field, current in the wire and the length of the wire.
