A weakly magnetised steel rod is tapped several times with a hammer.
What effect will this have on the magnetism of the rod under the two conditions shown in the table?
| The rod is held parallel to a strong magnetic field | The rod is held pointing East-West (at right-angles to the Earth's magnetic field) | |
|---|---|---|
| A | It becomes magnetised more strongly | It becomes magnetised more strongly |
| B | It becomes magnetised more strongly | It loses its magnetism |
| C | It loses its magnetism | It becomes magnetised more strongly |
| D | It loses its magnetism | It loses its magnetism |
Parallel: It becomes magnetised more strongly; East-West: It becomes magnetised more strongly
Parallel: It becomes magnetised more strongly; East-West: It loses its magnetism
Parallel: It loses its magnetism; East-West: It becomes magnetised more strongly
Parallel: It loses its magnetism; East-West: It loses its magnetism
