Does a Capacitor Have a Magnetic Field?
- Thread starter Fabio97
- Start date
In summary, the conversation is about determining the law describing the magnetic field as a function of the radius into a capacitor. The capacitor is in an active circuit with two round parallel plates, and there are no numerical values given. It is unclear if there are missing words in the translation or if there is a figure of the circuit accompanying the question. Possible variations of the question include determining the law for the magnetic field as a function of the circuit wire loop radius connected to the capacitor or as a function of the AC current flowing through the capacitor and the radius of the capacitor.

If this is the complete statement of the homework problem then you could start by listing the things that you don't know. For example,
1) What is the shape or geometry of the capacitor?
2) What is the the current flow into the capacitor?
3) Is the capacitor currently inside an active MRI?

The request is to write the law B(r), using the current i that flows in the circuit (the capacitor is in a activate circuit). The capacitor has two round parallel plates. We have no numerical values.

Welcome to the PF. 
For example:
I'm pretty sure that there are some words missing in the translation and/or there is a figure of the circuit that goes along with the question.Fabio97 said:

FAQ: Does a Capacitor Have a Magnetic Field?
What is a magnetic field for a capacitor?
A magnetic field for a capacitor is a region in space where a magnetic force can be observed due to the presence of a charged capacitor. This field is created by the movement of electric charges within the capacitor, and it can be measured and manipulated using scientific instruments.
How is the magnetic field for a capacitor created?
The magnetic field for a capacitor is created by the flow of electric charges within the capacitor. When a capacitor is charged, one plate becomes positively charged and the other becomes negatively charged. This creates an electric field between the plates. As the charges move back and forth between the plates, a magnetic field is created perpendicular to the electric field.
What factors affect the strength of the magnetic field for a capacitor?
The strength of the magnetic field for a capacitor is affected by the amount of charge on the plates, the distance between the plates, and the material of the plates. A larger charge, smaller distance, and higher permeability material will result in a stronger magnetic field.
How can the magnetic field for a capacitor be measured?
The magnetic field for a capacitor can be measured using a magnetic field sensor, such as a magnetometer or a Hall effect sensor. These instruments can detect and measure the strength and direction of the magnetic field produced by a charged capacitor.
Can the magnetic field for a capacitor be controlled?
Yes, the magnetic field for a capacitor can be controlled by changing the amount of charge on the plates or by adjusting the distance between the plates. By altering these factors, the strength and direction of the magnetic field can be manipulated. This is useful in various applications, such as in electronic devices and medical equipment.
