Net Magnetic Force on Rect. Current Loop

In summary, a rectangular current loop with dimensions L=0.40 m and W=0.19 m is placed near a long, straight wire (d=0.10 m) with a current of 10 A. The current in the loop is 20 A. Using the formula F=IlB, we can find the net magnetic force acting on the loop by considering the forces on the longer sides of the rectangle, as the forces on the shorter sides cancel each other out. The attached drawing would provide further clarification.

A rectangular current loop (L=0.40 m and W=0.19 m) is located near a long, straight wire (d=0.10) that carries a current of 10 A (see the drawing). The current in the loop is 20 A. The Determine the magnitude of the net magnetic force that acts on the loop.

i was chugging my B from the wire into f=IlB

We don't have the drawing (couldn't u attach it ?).It would make much difference how the straight conducting wire would be located wrt the rectangle...

You are using the correct formula. Find the force on each side of the rectangle and find the net force. You will see that the forces on the shorter sides cancels each other. So you have to consider the forces on only the longer sides of the rectangle.
 

What is the definition of net magnetic force on a rectangular current loop?

The net magnetic force on a rectangular current loop is the sum of all the individual magnetic forces acting on each segment of the loop, taking into account both the direction and magnitude of each force.

What factors affect the net magnetic force on a rectangular current loop?

The net magnetic force on a rectangular current loop is affected by the strength of the current, the size and shape of the loop, the strength of the external magnetic field, and the orientation of the loop with respect to the magnetic field.

How do you calculate the net magnetic force on a rectangular current loop?

The net magnetic force on a rectangular current loop can be calculated using the equation F = I * L * B * sin(theta), where I is the current, L is the length of the loop, B is the external magnetic field, and theta is the angle between the loop and the magnetic field.

What is the direction of the net magnetic force on a rectangular current loop?

The direction of the net magnetic force on a rectangular current loop is perpendicular to both the direction of the current and the external magnetic field. This can be determined using the right-hand rule.

How can the net magnetic force on a rectangular current loop be increased or decreased?

The net magnetic force on a rectangular current loop can be increased by increasing the strength of the current, the size of the loop, or the strength of the external magnetic field. It can be decreased by decreasing any of these factors or by changing the orientation of the loop with respect to the magnetic field.
