The nail picks up the paper pieces. Chose the correct explanation for this. (9a) Question 4 options: A Battery is a source of magnetism, which transferred to the iron nail to induce magnetic field and nail becomes a magnet B The Potential difference created by the battery polarizes the wire and nail and so picks up the paper pieces. C Potential difference provided by the battery causes electrons to move through the wire. Moving electrons create both Electric and Magnetic field causing nail becomes a magnet. D Battery provides the source of magnetism that magnetizes the wire leaving the nail and transfers this magnetism to the nail, causing the nail to become a magnet

Question 4 options:
|
A
|
Battery is a source of magnetism, which transferred to the iron nail to induce magnetic field and nail becomes a magnet |
|
B
|
The Potential difference created by the battery polarizes the wire and nail and so picks up the paper pieces. |
|
C
|
Potential difference provided by the battery causes electrons to move through the wire. Moving electrons create both Electric and Magnetic field causing nail becomes a magnet. |
|
D
|
Battery provides the source of magnetism that magnetizes the wire leaving the nail and transfers this magnetism to the nail, causing the nail to become a magnet. |
Potential difference is defined as the amount of work done in moving a unit charge from one point to another.
