q15_c0 | The aluminum piece on the left has greater initial power than the aluminum piece in the middle. |
q15_c1 | The aluminum piece on the left is subject to force in the external magnetic field but the aluminum piece in the middle is unforced. |
q15_c2 | The aluminum sheet on the left has a small area, and the induced electromotive force is small, so the resistance it receives is small. |
q15_c3 | The aluminum piece in the middle experiences resistance in the magnetic field, but the aluminum piece on the left does not experience magnetic force. |
q15_c4 | The structure of the aluminum sheet on the left limits the path of the induced current, resulting in no or much less induced current. |
q16_c0 | The middle plate stops sooner because the magnetic field exerts a direct mechanical force opposing its motion; replacing it with brass would cause it to stop even sooner due to increased magnetic interactions. |
q16_c1 | The middle plate stops sooner due to magnetic hysteresis losses as it moves through the magnetic field; replacing it with brass would cause it to stop later because brass is less susceptible to hysteresis losses. |
q16_c2 | The middle plate stops sooner due to eddy current damping opposing its motion; replacing it with brass, which has higher electrical resistivity, would cause it to swing shorter because larger eddy currents would be induced, leading to more damping. |
q16_c3 | The middle plate stops sooner because the magnetic field exerts a direct mechanical force opposing its motion; replacing it with brass would cause it to stop later due to decreased magnetic interactions. |
q16_c4 | The middle plate stops sooner due to eddy current damping opposing its motion; replacing it with brass, which has higher electrical resistivity, would cause it to swing longer because smaller eddy currents would be induced, leading to less damping. |
