Magnetic Force Direction Question

In summary, the conversation discusses a problem involving a wire with a length of 12.0cm, a magnetic field of 0.0720 T, and a current of 21.0 A. The wire experiences a magnetic force of 0.104 N [up] and the direction of the magnetic field is being sought. The relevant equation is B = IlBsin(theta) and the right hand rule may also be applicable. The problem is at a 4U level in Canada or grade 12.

Homework Statement


r= 0.12m
B = 0.0720T
I = 21.0A
Fm= 0.104 N [up]

A magnetic force of 0.104 N [up] acts on a 12.0cm long wire that runs[N 10 degrees E] through a magnetic field of 0.0720 T. If the current in the wire is 21.0 A, then what is the direction of the magnetic field?

This physics Level is 4U in Canada, or grade 12.


Homework Equations


B = IlBsin(theta)
Not sure what other equations to use.
Right hand rule might be relevant but not sure how to apply it.


The Attempt at a Solution


I am completely stumped and do not know where to start.

You need an equation between magnetic field strength and magnetic force. And watch out because you need to know directions of these vectors as well as just a formula.
 

Related to Magnetic Force Direction Question

1. 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 current.

2. How can I determine the direction of the magnetic force?

You can use the right-hand rule to determine the direction of the magnetic force. Point your thumb in the direction of the current, your fingers in the direction of the magnetic field, and the direction your palm is facing will be the direction of the magnetic force.

3. Does the direction of the current affect the direction of the magnetic force?

Yes, the direction of the current affects the direction of the magnetic force. The direction of the magnetic force is always perpendicular to both the direction of the current and the direction of the magnetic field.

4. Can the direction of the magnetic force be reversed?

Yes, the direction of the magnetic force can be reversed. This can happen when the direction of either the magnetic field or the current is reversed.

5. How does the direction of the magnetic force affect the motion of a charged particle?

The direction of the magnetic force can affect the motion of a charged particle by causing it to move in a circular or helical path, depending on the angle between the particle's velocity and the magnetic field. The force can also cause the particle to change direction or speed up/slow down.
