· Titanium is weakly attracted to magnets as it is a paramagnetic material. The main reason for its paramagnetic nature is its electronic configuration with 4 unpaired electrons, as paramagnetism depends on unpaired electrons. The second reason is its magnetic moment ie; 1.73 BM. Titanium is paramagnetic in its -1, +2 and +3 oxidation states.
