Question

An 0.050 m long wire carrying current of 30 A is placed in a uniform magnetic field, B = 0.80 T, such that the wire is oriented so it's length runs perpendicular to the field.  Find the magnitude of the force felt by this segment of wire.

Answer 1

Hi Mary!

 

This one is basically plug-n-chug.  The formula for the magnetic force (F_B) on a length of wire L with current i placed in uniform magnetic field B, with an angle θ between the current and the field is:

 

F_B = iLBsin(θ)

 

You are given all of these quantities, so all you need to do is drop them in and calculate.  Good luck!  And let me know if you would like to check an answer.
