Homework Statement



Suppose you have three closed loops (ring-like) Each one has current going through it. They are set parallel to each other and the same distance away from each from each other. Suppose also the current through the one in the middle loop and the one on the right loop move counterclockwise if we looked at the loops from the right side. However, the left lopp's current is opposite to the other rings (clockwise as seen from the right side too) The question is what is going to happen to the previous configuration? Is any of the loops going to rotate if we supposed that their centers are stationary?

Homework Equations



I know F=IVxB

The Attempt at a Solution



I tried applying the formula, but the force direction I get is always perpendicular to the rings (no tangential force) which means no rotation will occur but the answer says that the left ring (the one with opposite current direction) will rotate?!

The force due to the current in each loop will cause a torque on the loop, which will cause it to rotate. The left loop will experience a clockwise torque due to the current in the middle and right loops, while the other two loops will experience an equal and opposite counterclockwise torque. Therefore, the left loop will rotate, while the other two remain stationary.
 

What is current through three closed loops?

Current through three closed loops refers to the flow of electric charge through three separate and connected paths, creating a continuous circuit. It is measured in amperes (A) and is a fundamental concept in electricity and magnetism.

How is current through three closed loops calculated?

Current through three closed loops is calculated using Ohm's Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R). In the case of three closed loops, the total current is the sum of the individual currents through each loop.

What factors affect the current through three closed loops?

The current through three closed loops is affected by several factors, including the voltage of the power source, the resistance of the circuit elements, and the number of branches or loops in the circuit. Changes in any of these factors can alter the amount of current flowing through the circuit.

How does the current through three closed loops change over time?

The current through three closed loops can change over time due to various factors, such as changes in the power source, temperature changes affecting resistance, or the addition or removal of circuit elements. It is important to constantly monitor and adjust the current to ensure the proper functioning of the circuit.

What are some practical applications of understanding current through three closed loops?

Understanding current through three closed loops is crucial in the design and operation of electrical circuits, such as in household wiring, electronic devices, and power grids. Additionally, knowledge of current through three closed loops is essential in fields such as electrical engineering, physics, and renewable energy research.
