I uploaded the question i have to answer.

I am given a daigram of a simple DC electric motor.

I am asked to find which way the coil will spin at certain points

I have been using the right hand palm rule where my thumb points in the direction of the current and my fingers in the direction of the field. Thus the force exerted on the coil at certain poits will be in the direction of my palm.

The field always goes from North to south. and the current is shown so at point X the force should be out of the page. But the answers say its into the page.

is this right?
