In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
Transformer or instrument transformer. It can increase and decrease current output.
A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
try RHEOSTAT
Electromagnets are never used to increase or decrease the voltage in a circuit. These magnets in conjunction with a rotating device (an armature) can create a voltage but the do not have any effect on a voltage.
To decrease the resonant frequency of any tuned circuit, increase the inductance and/or increase the capacitance.

It causes a proportional increase in current.
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Correct Answer= "the current will increase"
