Question on: JAMB Physics - 2001
The force on a current carrying conductor in a magnetic field is greatest when the
A
conductor makes an angle of 60° with the field
B
force is idependent of the angles between the fields and the conductor
C
conductor is parallel with the field
D
conductor is at right angle with the field
Ask EduPadi AI for a detailed answer
Correct Option: D
The force on a current-carrying conductor in a magnetic field is given by the equation:
F = B I L sin(θ)
where:
* F is the force
* B is the magnetic field strength
* I is the current
* L is the length of the conductor
* θ is the angle between the conductor and the magnetic field
The force is greatest when sin(θ) is at its maximum value, which is 1. This occurs when θ = 90°, meaning the conductor is at a right angle with the field.
