practice question answer?

For questions like this I'm wondering whether a decrease in current would be implied from the increase in voltage, since P=VI and its a power source.
Also if this is the case would an increase in voltage always imply a decrease in current or not
I dont have the answers to the practice exam but I'd assume C is right

I'm going to cautiously say that in this case, an increase in voltage does not imply a decrease in current. Why can't A be true?

I'm pretty sure that option D is correct.

Since the resistance of the coil is not going to change, Ohm's law (V=IR) tells us if we increase our voltage, the current will also be increased.

Since the force exerted on the wire is given by: F=nBIL, increasing the magnetic field strength and current will result in a greater force.
