How would you determine the magnitude of the magnetic force on each of the four sides?
A square coil of wire containing a single turn is placed in a uniform #0.20 T# magnetic field, as the drawing shows. Each side has a length of #0.32 m# , and the current in the coil is #12 A# .
A square coil of wire containing a single turn is placed in a uniform
1 Answer
Upper and lower sides
Both vertical sides
Explanation:
Lorentz Force equation describes the force experienced by a charge particle having charge
In the problem it is given that there is there is no electric field.
Also, it is a case of wire carrying an electric current
where
For horizontal sides of the coil:
For vertical sides, cross product of vectors vanishes as
-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-
For sake of completeness.
Direction of the force is given by the cross product of the two vectors. It can also be found with the help of right hand rule as in the picture below.
Direction of the force experienced by upper side is out of the paper. Whereas for the lower side it is in to the paper.
