Which statement best describes the orientation of a magnetic field around a circuit when a capacitor is used?
capacitors prevent current from moving through a circuit.
magnetic fields reverse when a capacitor charges or discharges.
electrical current decreases the storage capacity within the capacitor.
electrical current from a capacitor minimizes magnetic fields.

Magnetic fields reverse when a capacitor charges or discharges.

Explanation:

When capacitor is connected in a circuit then during the charging of the capacitor the current flows into it that will charge the capacitor to its full capacity

Due to this charging of the capacitor the current will decrease and after complete charging the current comes to zero

Now when same circuit goes for discharging then the direction of the current will reverse and the plate charge will start decreasing.

finally the current again disappears and magnetic field will change its direction when the direction of the current will reverse

so correct answer will be

Magnetic fields reverse when a capacitor charges or discharges.
