What do all magnets have in common? Select all that apply magnetic domains are aligned
magnetic domains are not aligned
movement of protons creates a magnetic field
all magnets have opposite poles (a North pole and South pole)
movement of electrons creates a magnetic field
moving electrons generate magnetic fields

all magnets have opposite poles (a North pole and South pole)

movement of electrons creates a magnetic field

Explanation:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
