Hi(adsbygoogle = window.adsbygoogle || []).push({});

Ok so i came across this question which asks you to find the force on electrons in a wire which is moving in a magnetic field, hence the opposite to the direction of the current. I worked out using The right hand rule that the current would be going from point P to Q, which was write. However the next part asked to find if the potentials of p or q was greater, i said that p was bigger because the definition of potential is the work done per unit charge to bring a small test charge from infinity to that point, hence you would need less work to bring a charge to Q(the negative terminal) than to p (the positive terminal). But the answer says it that the potential of p is less than the potential of q, but gives no explanation. Why is it that the potential of p is less than the potential of Q?

Thanks
