Increasing the field or increasing the current will decrease the force on the conductor.
True
False
Can not say anything
Insufficient data
False
The force exerted on a current-carrying conductor in a magnetic field is directly proportional to both the magnetic field strength and the current flowing through the conductor. Therefore, increasing either the field or the current increases the force rather than decreasing it.

F=BIlsin(╬╕) тАФ The magnitude of the magnetic force on a straight conductor
FтИЭB тАФ Force is directly proportional to magnetic flux density
FтИЭI тАФ Force is directly proportional to current
According to the Lorentz Force Law for a conductor, the force F is given by the cross product of the current vector and the magnetic field vector. When the current and the magnetic field are perpendicular, the magnitude is defined by F=BIl. Since F is linearly proportional to B (flux density) and I (current), any positive change in these parameters results in a proportional increase in the force magnitude.
Magnetic force is a direct outcome of the interaction between the charge carriers in the conductor and the external magnetic field.
The maximum force occurs when the current direction is perpendicular to the magnetic field vector (theta=90┬░\┬░).
Fleming's Left-Hand Rule is used to determine the direction of the force.

Option A is incorrect because the relationship between force, current, and magnetic field is direct, not inverse.
This concept is fundamental to the design of electromagnetic machines in power systems.
B is correct тАФ The force on a current-carrying conductor in a magnetic field is directly proportional to the current and the magnetic field strength, meaning increasing either will increase the force.
Always remember that in electromagnetics, most force and torque equations follow a direct proportionality (FтИЭI); watch out for inverse square relationships, which usually apply only to distance, not intensity.
