Direction of magnetic force

In summary, to find the direction of the magnetic force on a current loop experiencing a torque, you can use the right hand rule. Curl your fingers in the direction of the current flow, and your thumb will point in the direction of the loop's magnetic dipole moment. This force will try to align the dipole moment with the external magnetic field. Additionally, the direction of the force on a charged particle in a magnetic field can be determined using the formula \vec{F} = \vec{v} \times \vec{B}, where \vec{v} is the velocity and \vec{B} is the field. Applying the right hand rule can help determine the direction of this force.

how do you find the direction of the magnetic force on a current loop..a loop that experiences a torque?
i know you use some kind of right hand rule but I am confused


also..the direction of a charged particle in a magnetic field


please helpppppp

its the right hand rule, where ur fingers are in the direction of the current flow...im pretty sure

If you curl the fingers of your right hand in the direction the current flows around the loop, then your thumb points in the direction of the loop's magnetic dipole moment. The force on the loop will tend to align the dipole moment vector to be in the same direction as the external magnetic field the loop is sitting in.

The direction of the force on a charged particle in a magnetic field is:

[tex]\vec{F} = \vec{v} \times \vec{B}[/tex]

where [itex]\vec{v}[\itex} is the velocity and [itex]\vec{B}[\itex] is the field.

Do you know how to apply the right hand rule to cross products such as this one?
 

What is the direction of the magnetic force?

The direction of the magnetic force is perpendicular to both the direction of the magnetic field and the direction of the moving charged particle. This is known as Fleming's left-hand rule.

How is the direction of the magnetic force determined?

The direction of the magnetic force is determined by the cross product of the magnetic field vector and the velocity vector of the charged particle.

Does the direction of the magnetic force change with the direction of the magnetic field?

Yes, the direction of the magnetic force changes with the direction of the magnetic field. If the direction of the magnetic field is reversed, the direction of the magnetic force will also be reversed.

What is the relationship between the direction of the magnetic force and the velocity of the charged particle?

The direction of the magnetic force is always perpendicular to the velocity of the charged particle. This means that the magnetic force will not change the speed of the particle, but will only change its direction of motion.

Can the direction of the magnetic force be changed?

Yes, the direction of the magnetic force can be changed by changing the direction of the magnetic field or by changing the direction of the velocity of the charged particle.
