When capacitor is leaking ie, when charge is leaking or when it is discharging then will there be any magnetic field between the parallel plates of capcitor?
But from here nothing comes to my mind. I am almost clueless from here.willem2 said:So, there is displacement current because the electric field changes and there is the leakage current. you should be able to work out what the magnetic field should be. It seems your teacher also did this.
If you want to compute the magnetic field everywhere between the plates, you will have to assume the leakage is the same everywhere.
Can you show us the calculation that your teacher did to conclude that it is zero?Anurag00 said:then my teacher gave us the answers which gave zero to be the correct answer...

He just gave the answer verbally, not the solution.berkeman said:Can you show us the calculation that your teacher did to conclude that it is zero?
Let me try again.willem2 said:You must have seen an equation where this displacement current appears. You should be able to find everything what is needed to work out the displacement current, with what you already know about capacitors.
A magnetic field in a capacitor is a region in space where magnetic forces are present due to the movement of charges in the capacitor's electric field.
A magnetic field is generated in a capacitor when charges flow through the capacitor's conducting plates, creating a circulating current. This current produces a magnetic field that is perpendicular to the electric field between the plates.
The direction of the magnetic field in a capacitor is perpendicular to the electric field and depends on the direction of the current flowing through the plates. It follows the right-hand rule, where the fingers of the right hand curl in the direction of the current and the thumb points in the direction of the magnetic field.
The magnetic field in a capacitor can affect its operation in a number of ways. It can cause power losses due to eddy currents, impact the capacitance and voltage rating of the capacitor, and introduce noise in electronic circuits.
Yes, a capacitor's magnetic field can be controlled by altering its design. For example, using a ferromagnetic material in the capacitor's plates can concentrate the magnetic field, or using a coaxial or solenoid capacitor design can reduce the effects of the magnetic field on the capacitor's operation.
