There are currently two main types of oval magnets on the market. One is spherical and used as children’s toys; these are typically made of ferrite and do not have very strong magnetic properties. The other type, which you are looking at now, is not spherical but flat; it is made of neodymium and is primarily used in industrial applications and equipment, and can be drilled.
Regarding neodymium oval magnets, they are typically magnetized along the thickness, but some applications may require strong magnetic fields along the sides, meaning they are magnetized along the width.
