A generator, in general.
Dc chopper is a static device which converts constant dc source to variable dc.
It is a variable resistance device which control the flow of current
A chopper or DC-DC converter is a circuit or technique used to convert a constant DC signal into a variable DC signal where by using switching technique known as PWM(pulse width modulation). A chopper is a static device that converts dc input into dc output voltage directly. A chopper may be thought of as an ac transformer since they behave the same.

Variable is, logically, something that varies, that is to say, is not constant over time. Controlled variable, in the control field theory, is a variable measure that is, or that needs to be, controlled. Like a voltage that you need to keep under 10Volts because some devices in the setup have an amplitude limitation. Manipulated variable is usually a measure, a variable that you can measure. For example, if you can measure the voltage in the experimental setup then you can manipulate it, like using it to power a device. Constant variable, i think this is not very correct, a mathematician's opinion might be needed. For me is a variable, thus something that is variable over time, that under certain conditions becomes constant, thus stops varying according to time.
Yes, they ARE magnetic
the device is a dedle on compass
A storage device.
A compass is a device that indicates the direction of the magnetic flux. It aligns with the Earth's magnetic field and points towards the magnetic North Pole.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.

Yes it is a portable device
The magnet pull strength of the new magnetic device is 50 pounds.
It is the magnetic elements in a magnetic disk that are used to store information.
