*acts on an object by something - in the case of the magnetic force this is typically referring to the force from a magnetic field on a charge or current (as we will see in the next pages of notes). NOTE that a moving charge cannot feel a force from the magnetic field it produces (for the same reason why you can float or fly by pulling on your toes). **In order for a moving charge to feel a force, there must be an external magnetic field.** | *acts on an object by something - in the case of the magnetic force this is typically referring to the force from a magnetic field on a charge or current (as we will see in the next pages of notes).
