Has magnetism (5)

I believe the answer is:

pulls

I'm a little stuck... Click here to teach me more about this clue!

'has' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for pulls that I've seen before include "Tugs something towards oneself" , "Tows" , "Attracts" , "Draws" , "Hauls" .)

I've seen this clue in the Evening Standard.
