A.)For a charge moving with velocity v, the magnetic field lines are circles centered on the line of v and lying in planes perpendicular to this line.
True or False
B.)The net force on a magnetic dipole (e.g. a small magnet) in a uniform magnetic field is zero.
True or False
C.)To determine the direction of the force on a straight current-carrying wire, we point the fingers of our right hand in the direction of the magnetic field, curl our fingers towards the direction of the current, and our thumb will point in the direction of the force.
True or False
D.)If a magnetic dipole moment is oriented such that the vector is pointing directly at you, you will observe the current to flow in a
Clockwise direction or Counter-Clockwise direction

Force on Moving Charges in a Magnetic Field
Magnets exert forces on other magnets even though they are separated by some distance. Usually the force on a magnet (or piece of magnetized matter) is pictured asthe interaction of that magnet with the magnetic field at its location (the field being generated by other magnets or currents). More fundamentally, theforce arises from the interaction of individual moving charges within a magnet with the local magnetic field. This force is written ,where is the force, is the individual charge (which...
