Hi all,

I want to start off by saying that I am not too good with physics, so while explaining, if terms could be kept simple I would really appreciate it. :)

Here are my questions:

Can an electromagnet repel a permanent magnet with any significant amount of force? My target is around 175psi of force. Can this be done using magnets?

Furthermore, I need to move the permanent magnet 3". Is this possible?

Also, is there a limit to how quickly an electromagnet can be pulsed? I need things to be instant like a light switch.

I hope I asked my questions in a clear manner, but if anything isn't understood, feel free to ask for clarification.

Thanks a ton :)

Sounds very clear. The only limit to the repulsive force is the size of the magnetics / how much current you can provide to the electromagnet (there are also material issues, like the electromagnet melting... but you prolly won't have to worry about that).
175psi is a lot of force, so it would take a lot of power.. but its doable. As is 3".

It couldn't be "instant," but it would be very fast.. like hundredths of a second or less.

## 1. What are electromagnetic forces?

Electromagnetic forces are the forces that act between electrically charged particles. They are responsible for the interactions between atoms and molecules, and are essential for the functioning of many technological devices.

## 2. How do electromagnetic forces work?

Electromagnetic forces are carried by particles called photons. These particles are exchanged between charged particles, causing them to either attract or repel each other depending on their charges.

## 3. What are some examples of electromagnetic forces?

Some examples of electromagnetic forces include the force that holds electrons in orbit around the nucleus of an atom, the force that causes magnets to attract or repel each other, and the force that allows for the transmission of radio waves.

## 4. How do electromagnetic forces affect daily life?

Electromagnetic forces play a crucial role in many aspects of our daily lives. They are responsible for the functioning of electronic devices such as phones and computers, the generation and transmission of electricity, and even the light that we see.

## 5. Can electromagnetic forces be shielded?

Yes, electromagnetic forces can be shielded by materials that are able to block the movement of charged particles. This is why we use materials like metal to shield sensitive electronic devices from interference.
