The diagram depicts a copper coil with a short circuit swinging around an axis at right angles to a strong magnetic field. This motion produces a current in the coil. What effect, if any, does this induced current have on the coil?
- AThe induced current has no effect on the movement of the coil because copper is non-magnetic.
- BThe induced current produces a magnetic field of constant magnitude in the coil.
- CThe induced current produces forces that assist the change causing it.
- DThe induced current produces forces that oppose the changes causing it.
