Force Acting on Current Carrying Conductor: Practice Problem & Solution
A square current carrying loop is suspended in a uniform magnetic field acting in the plane of the loop. If the force on one arm of the loop is $vec{F}$, the net force on the remaining three arms of the loop is: (2010 Pre)
Solution Explained:
To solve this problem, we apply the core principles of Force Acting on Current Carrying Conductor. Understanding the underlying formula is key to arriving at the correct answer below:
The net magnetic force on a closed current loop in a uniform magnetic field is always zero.
Therefore, $\vec{F} + \vec{F}_{\text{remaining}} = 0$, which gives $\vec{F}_{\text{remaining}} = -\vec{F}$.
