6 FAQs about [Magnet capacitor charging]

Can a capacitor create a magnetic field?

I saw an exercise example where we changed the voltage across a capacitor and thus created a magnetic field between them.But some websites state that as long as there is no current - charge movement at the place of interest, there is no magnetic field being created. I read the same about the capacitor in particular.

Why does a capacitor have a curly magnetic field?

Is there a current when a capacitor is charging?

When a capacitor is charging there is movement of charge, and a current indeed. The tricky part is that there is no exchange of charge between the plates, but since charge accumulates on them you actually measure a current through the cap. If you change the voltage, isn't there a current?

How do you calculate the magnetic field of a capacitor?

Equating the left hand side and the right hand side gives a value for the magnetic field at a distance r from the central axis of the capacitor B = μoIr 2πR2 B = μ o I r 2 π R 2 for 0 ≤ r ≤ R 0 ≤ r ≤ R and with r=R this gives the familiar B = μoI 2πR B = μ o I 2 π R

How many capacitors should a magnetic system use?

Furthermore, different magnetic loads may require different amounts of capacitors to be used, and the system should only use as many capacitors as needed. Power transistors controlled by a micro controller will be used to coordinate the charging and discharging process.

Why does a capacitor have a higher electric field than a current?

Because the current is increasing the charge on the capacitor's plates, the electric field between the plates is increasing, and the rate of change of electric field gives the correct value for the field B found above. Note that in the question above dΦE dt d Φ E d t is ∂E/∂t in the wikipedia quote.
