Which of the following statements are true concerning electromagnetic induction? Check all that apply?


A. It is possible to induce a current in a closed loop of wire located in a uniform magnetic field by either increasing or decreasing the area enclosed by the loop.
B. It is possible to induce a current in a closed loop of wire by change the orientation of a magnetic field enclosed by the wire.
C. It is possible to induce a current in a closed loop of wire by changing the strength of a magnetic field enclosed by the wire.
D. It is possible to induce a current in a closed loop of wire without the aid of a power supply or battery.
E. It is possible to induce a current in a closed loop of wire located in a uniform magnetic field.

Part C
It is possible to induce a current in a closed loop of wire by changing the strength of magnetic field enclosed by the wire.

Part D
It is possible to induce a current in a closed loop of wire without the aid of power supply or battery.

Part E
It is not possible to induce a current in a closed loop of wire located in a uniform magnetic field.
