# Interactions between charge and magnetic field

I know that a charged particle moving in a magnetic field experiences a magnetic force that is the cross product of the velocity of the charge and the magnetic field. My understanding is that the magnetic field exerts a magnetic force on the particle because of its electric charge.

But a moving particle also generates a magnetic field of its own. My textbook seems to suggest that the magnetic field of the moving particle creates an imbalance in the magnetic field it is travelling through, so the field tries to "balance" the field by exerting a force on the charge.

So which explanation is correct?

Thanks

• The first one. The second one does not enter the equations of motion ;-) Jul 30, 2018 at 8:01
• If the textbook is written in English, I'd be interested to know its name and author(s). Jul 30, 2018 at 9:43
• A quotation from the textbook would be helpful. Jul 30, 2018 at 10:10
• The resulting (total) magnetic field (for another particle) depends on the velocity direction of the first particle, so it is not correct to speak of "balabce" or "compensation", whatever. Jul 30, 2018 at 10:13
