How strong does a permanent magnet/electromagnet need to be in order to see the effects of magnetic braking on a flat metal pendulum?
Magnetic Braking: Pendulum Strength Req. for Effects
In summary, the strength of a permanent magnet or electromagnet needed to see the effects of magnetic braking on a flat metal pendulum depends on various factors and cannot be determined without more specific information. It is recommended to do some background research on the topic and ask specific questions for a more accurate estimate.

With that wealth of detailed information in your question, I'd say the answer is "some".

As you can tell, we would need a lot more information in order to give you a ballpark estimate. But even better would be if you read through some background information (encyclopedia-type) articles, and link to them and ask specific questions about what you don't understand. The Wikipedia article on "Eddy Current Brake" looks to be a good place to start.
Related to Magnetic Braking: Pendulum Strength Req. for Effects
1. What is magnetic braking?
Magnetic braking is a process in which the movement of a pendulum is slowed down or stopped by the application of magnetic forces.
2. How does magnetic braking work?
Magnetic braking works by using a magnetic field to induce eddy currents in a conductive material, such as metal. These eddy currents create a magnetic field that opposes the original magnetic field, resulting in a force that slows down the movement of the pendulum.
3. What is the strength requirement for magnetic braking to have an effect on a pendulum?
The strength requirement for magnetic braking to have an effect on a pendulum depends on several factors, such as the strength of the magnetic field, the size and material of the pendulum, and the distance between the magnetic field and the pendulum. Generally, a stronger magnetic field will result in a greater braking effect on the pendulum.
4. Can magnetic braking be used to completely stop a pendulum?
Yes, magnetic braking can be used to completely stop a pendulum's movement. However, this would require a very strong magnetic field and precise positioning of the pendulum and the magnetic field. In most cases, magnetic braking is used to slow down the movement of a pendulum rather than stopping it completely.
5. What are the practical applications of magnetic braking?
Magnetic braking has various practical applications, such as in roller coasters and other amusement park rides, where it is used to control the speed and movement of the ride. It is also used in some types of brakes for vehicles, and in some industrial processes where precise control of movement is required.
