Question about protection spells.

Please forgive me if I am in the wrong area I have just registered. I would like to know if I place a protection spell on an item if the person it's about has to wear it or if it would work if wore it. For awhile I have had feelings a friend close to me would be hurt in someway I am not sure how exactly. I have feelings deep inside that are hinting me towards something that involves him. If I did a protection spell on something and I wore it on my person would it still protect him or would he have to wear it himself.

Thanks in advance.....
