Question

In this simulation, you can examine the magnetic field created by the current in a solenoid, which is a cylindrical coil of wire. Instead of using a spiral-shaped coil, the simulation approximates the coil with a stack of seven single loops. The plane of each loop is parallel to the x-z plane, with a radius of either 60 cm or 25 cm, and the displayed field is in the x-y plane. Choose from options below.

1.In the ideal capacitor changing the distance between the plates does not affect the electric field. In the ideal solenoid changing the radius of the solenoid does not affect the magnetic field.
2.The electric field in the capacitor is produced by static charges, while the magnetic field in the solenoid is produced by moving charges.
3.Doubling the magnitude of the charge on each plate of the ideal capacitor doubles the electric field. Doubling the current in each loop of the solenoid doubles the magnetic field.
4.In both ideal devices the fields are uniform inside the devices and zero outside.
5.The direction of the uniform electric field in the capacitor is parallel to the plates making up the capacitor, while the direction of the uniform magnetic field is parallel to the axis of the solenoid.
6.A charged particle launched into the uniform field between the plates of the parallel-plate capacitor will follow a parabolic path. The same is true for a charged particle launched into the uniform magnetic field inside the solenoid.

Explanation / Answer

The following statements correctly compare the ideal parellel - plate capacitor to the ideal solenoid. 2) The electric field in the capacitor is produced by static charges,while the magnetic field in the solenoid is produced by moving charges. 3) Doubling the magnitude of the charge on each plate of the ideal capacitor doubles the electric field. Doubling the current in each loop of the solenoid doubles the magnetic field. 4) In both ideal devices the fields are uniform inside the devices and zero outside. 2) The electric field in the capacitor is produced by static charges,while the magnetic field in the solenoid is produced by moving charges. 3) Doubling the magnitude of the charge on each plate of the ideal capacitor doubles the electric field.
