Force on a Current Carrying Conductor

In summary, there are two situations that would result in a magnetic force on the wire pointing due north: when the current in the wire flows straight down and the magnetic field points due west, and when the current in the wire flows due west and slightly up and the magnetic field points due east. These can be determined using the right hand rule or left hand rule. The third situation, where the current flows due east and the magnetic field points straight down, does not result in a magnetic force on the wire.

Homework Statement



Which of the following situations would result in a magnetic force on the wire that points due north?

Check all that apply.

Current in the wire flows straight down; the magnetic field points due west.
Current in the wire flows straight up; the magnetic field points due east.
Current in the wire flows due east; the magnetic field points straight down.
Current in the wire flows due west and slightly up; the magnetic field points due east.
Current in the wire flows due west and slightly down; the magnetic field points straight down.

Homework Equations



Right hand rule of left hand rule

The Attempt at a Solution



I know that the third one is correct but it says that the answer is wrong which means there is atleast one other correct answer but I have NO CLUE which one that is. Please help.

A. When the current is up and the magnetic field is East, the force is North.
B. When both current and field in A are reversed, the force is North.
If the current is mostly West and slightly up you have situation A but a weaker force to the North.
 

What is force on a current carrying conductor?

Force on a current carrying conductor is the force exerted on a conductor due to a magnetic field. This force is perpendicular to both the direction of the current and the magnetic field.

What factors affect the force on a current carrying conductor?

The force on a current carrying conductor is affected by the strength of the magnetic field, the current flowing through the conductor, and the length of the conductor in the magnetic field.

How can the direction of the force be determined?

The direction of the force on a current carrying conductor can be determined using the right hand rule. Point your thumb in the direction of the current, and your fingers in the direction of the magnetic field. The direction your palm faces will indicate the direction of the force.

How is the force on a current carrying conductor calculated?

The force on a current carrying conductor can be calculated using the equation F = I * L * B * sin(theta), where I is the current, L is the length of the conductor, B is the magnetic field strength, and theta is the angle between the current and the magnetic field.

What are the practical applications of force on a current carrying conductor?

Force on a current carrying conductor has many practical applications, such as in electric motors, generators, and particle accelerators. It is also used in devices like speakers and headphones to convert electrical energy into mechanical motion.
