So to , for example, increase the voltage, do I need an electrical field or magnetic field, or combination of both?

I understand that with a varying magnetic field we can induce current in the wire, which will either oppose or lead the existing current, but is possible to change the voltage?

Hello, I am interested in knowing what happens ta wire trough which current is flowing, when an external magnetic, electrical or both , field is applied? Does the voltage or current change, can it be changed this way? Can you also provide some equations of this phenomenon, and also...

If I had an device which would be sensitive to the amount and intensity of the light absorbed, would it show the same value(assuming the proposed variable is dependent on the factors mentioned before) for a red surface and a white one(not mirror)(presume a red light is falling to the incident...

How about the intensity? Will it be the same?

If a red light drops on a red object, we know that all of the red light is reflected, and none is absorbed. But what happens if a red light drops on a white surface, is all of the red light reflected, will the intensity of the reflected light be the same? Or will the reflected light be of a...
