# Magnetism and force on a conductor

### Inertialforce

1. The problem statement, all variables and given/known data
The question is as shown on the attachment.

2. Relevant equations
F = BIL

3. The attempt at a solution
To find the magnitude of the force I used the equation "F = BIL" and then I put in the values for each (B=0.25, I=15, L=0.20) and I got an answer (magnitude) of 0.75. Then using the right hand rule I found the direction of the force to be pointing to the right.

I just want to make sure, I am doing this right? Because the next three questions on my worksheet are very similar to this one except I am finding different things and I am given different values.

Re: Magnetism

OK.
How did you apply the right hand rule?

Re: Magnetism

The way you found out the magnitude of the Magnetic Induction on the straight current carrying current is proper. Now, in order to find its direction, you need to apply Fleming's Left Hand Rule.
