Square Loop of Copper Wire Falls out of

In summary, Ryan is seeking help with a HW problem involving a square loop of copper wire in a magnetic field. He is trying to find the terminal velocity and has attempted to use the equation vf = vi + at, but has been reminded to balance the magnetic force against gravity instead.

Homework Statement


I am stuck on a HW problem. A square loop of copper wire falls out of a side 'a' and radius 'r' falls outside of a magnetic field 'B'. How does one find the terminal velocity?
B = 1.2T
a = 5cm
r = 1mm

Please help me set up this problem so I can solve it and figure out what is going on!

Thanks,
Ryan---

Hi Ryan! Welcome to PF! :smile:

Forget about acceleration!

Terminal velocity means that the acceleration is zero!

So just balance the magnetic force against gravity. :wink:

Ah! Failed to see the obvious.
Thanks!

1. What is a square loop of copper wire?

A square loop of copper wire is a square-shaped piece of copper wire that has been bent into a loop shape. It is commonly used in electrical circuits and as a component in various scientific experiments.

2. How does a square loop of copper wire fall out of something?

A square loop of copper wire can fall out of something if it is not securely attached or if there is a force acting on it that causes it to become detached. It can also fall out if it is not properly balanced or if there is a change in the environment, such as a change in temperature or pressure.

3. What causes a square loop of copper wire to fall out of something?

A square loop of copper wire can fall out of something due to a number of factors. These can include physical forces, such as gravity or friction, or changes in the environment, such as a change in temperature or pressure. It can also fall out if it is not securely attached or if it is unbalanced.

4. Is it common for a square loop of copper wire to fall out of something?

It depends on the specific situation and how the square loop of copper wire is being used. In general, if the loop is securely attached and properly balanced, it should not fall out easily. However, if there are external forces acting on it or if it is not properly secured, it may be more likely to fall out.

5. How is a square loop of copper wire used in scientific experiments?

A square loop of copper wire is commonly used in various scientific experiments, particularly in the fields of electricity and magnetism. It can be used to demonstrate concepts such as electromagnetic induction and the effects of changing magnetic fields. It can also be used as a component in electrical circuits to measure current or voltage.
