Hello list as argued in preceeding post the answer "is it magnetic" cannot be answered by yes or no. With a strong magnet the most magnetic Martian, Los Angeles, can be weakly attracted, due to its content of magnetite (1-2%), may be NWA817 also. Al the others are too weak (half a percent of magnetite or magnetic sulfide). For lunar I have no personal experience but regolith breccia can contain up to 2% of metallic iron, while maria basalt has one per mil at most. Therefore some lunar should be (weakly) attracted by NdFeB magnets. However this metal is heterogeneously distributed so some fragments will be attracted, some not. I have a quantitative magnetic chart for all meteorite types; ask me for the file off list.

As for the harm done by magnet on samples and the dubious utility of this test please refer to my February 16 post and subsequent discussion!
